Employee empowerment – Enables our workforce to improve, innovate, and communicate. KAIZEN FLOW

Standards – Standardized work forms the baseline for continuous improvement.

Improving Value for the Customer The five principles of lean thinking begin and end with the customer.

• • • •

6S – Formerly known as 5S + safety, this fundamental methodology is quite simple: sort, straighten, shine, standardize, and sustain. Visual management – Enables the teams to see what and how they are doing through visual control charts and other monitoring methods.

FUTURE STATE

Our lean principles and processes:

Know what the customer considers is willing Standardize Idealvalue, and to pay for Future State “Ultimate Map the Value Stream, analyzing theGoal” wastes that exist Future within the processes State Create flow through elimination of errors and waste Current Create pull system responding to customer demands State Continuously improve in pursuit of perfection

Waste elimination – G&H focuses on eight deadly wastes: defects, overproduction, waiting, non-value added processing, transportation, inventory excess, motion, and employee-related. Problem solving – G&H utilizes four approaches: plan, do, check, act (PDCA); 5-why analysis, fishbone diagrams, and simplified failure mode and effects analysis (FMEA). Kaizen – Japanese for “improvement”. Typically Kaizen events are scheduled activities to re-organize, re-arrange, or re-tool production to improve flow.

ABOUT US

QUALITY MANAGEMENT DELIVERING EXCELLENCE Combined with our vision of continuous improvement, the core principles and processes, systems and tools facilitate the operational excellence that delivers successful outcomes: customer satisfaction, shareholder satisfaction, employee engagement and a more robust supply chain. Quality Management System for Product and Sites G&H’s continued focus on quality management systems (QMS) across all of our UK and US manufacturing sites, as part of the accreditation standardization process benefits our customers in many ways: • • • • • •

Improved consistency Improved reliability Improved traceability Reduced risk Reduction of waste and downstream costs Improved sustainability

Our quality management strategy is constantly evolving, with the following four standards: ISO9001, AS9100C, OHSAS 45001 and ISO 14001, forming the basis of our current and wider deployment plans for the future.

ISO 9001

Aerospace Industry quality management system. G&H is gaining certification in facilities that serve the aerospace and space industries in addition to transitioning to Rev D.

AS 9100C

OHSAS 45001

Longer term plans exist for a wider site coverage for the International standard for the environmental management of our business.

Currently certified to ISO9001:2008, G&H in the process of transitioning to ISO9001:2015.

International standard for Occupational Health & Safety. 45001 will replace 18001 by the end of 2017, so in the meantime G&H have adopted 18001 as an aspirational target in preparation for the 45001 standard.

ISO 14001

Compliance G&H recognizes that compliance with export regulations, material sources, and material regulations around the world is an important activity. Legislative changes, worldwide, have driven the recent expansion of this function. Our compliance managers are focused on ensuring we provide the necessary documentation to support our customers. This information includes an ever-expanding range of regulations, of which these are the most common: • • • • • •

International Traffic in Arms Regulation (ITAR) UK Export Control Organization (UK ECO) US Export Administration Regulations (US EAR) EU Restriction of Hazardous Substances (RoHS) EU Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) Conflict Minerals Compliance (Section 1502 of the US Dodd-Frank Act of 2010)

Our sales staff, together with country-specific compliance managers, are able to readily provide customers with compliance information or documentation on request.

WORK IN PROCESS, NOT AN END STATE Continuous improvement is just that: continuously improving our products and our processes to improve flow, to remove waste, and to improve our products and services. As part of this activity a more proactive quality deployment within the product lifecycle is being realized. Inputs from the recent customer satisfaction survey are also being incorporated as part of this exercise. We look forward to updating our customers on our progress and to learn about how we can improve our systems to support our customers’ own lean initiatives.

ACOUSTO-OPTICS

TECHNICAL EXPERTISE AND MANUFACTURING CAPABILITIES G&H acousto-optic components are characterized by unmatched optical power handling, optical performance delivered consistently over time and in volume, and designs optimized for a wide variety of applications.

Acousto-optic products covering wavelengths from the ultraviolet to the infrared are available in a wide range of optical materials, including TeO2 grown in-house, to minimize distortion, scatter, and transmission loss. Depending on the product type, we optimize transducer geometry to drive the acousto-optic crystal: longitudinal (compressional) acoustic mode or shear acoustic mode. Special attention is given to the transducer orientation to maximize electrical to acoustic conversion efficiency. Cold weld metal bonding and thermal expansion coefficient matching are used to provide a strong, reliable, low-loss attachment of the piezoelectric transducer to the interaction material, improving durability over broad operating temperature ranges. We use technology such as apodized electrodes and phased array electrode designs to optimize the shaping of the acoustic field for each application, and wirebond the control electronics for a reliable, environmentally durable, low loss connection. Wirebonding also minimizes acoustic absorption at the transducer connection points. Device packaging is designed to minimize thermally-induced wavefront distortion and beam wander during operation, and to extend product lifetime. Transducers are impedance matched to 50 Ω to allow

for testing and use with industry standard RF equipment. RF drivers are specifically designed to drive our acousto-optic products at peak performance, with options customized to each application. Decades of experience working with OEM partners around the world has given us the understanding to develop, design, and manufacture for extremes of temperatures, radiation, shock, and vibration.

ACOUSTO-OPTICS

BEAM DEFLECTORS Designed for high speed, solid state scanning applications Acousto-optic beam deflectors (AOBD) offer precise angular control of an optical beam using RF drive frequency tuning. Up to two thousand spots can be resolved over an angular range of a few degrees for 1D and 2D scanning as well as beam deflection through a fixed angle. The scan speed can be as fast as a few microseconds. G&H beam deflectors offer highly uniform diffraction efficiency across the full scan angle, with consistent power throughput for scanning applications such as material processing and digital imaging. We manufacture devices based on tellurium dioxide crystals grown in-house for visible and near-infrared (NIR) wavelength applications. For optimal transmission in the ultraviolet (UV) we offer fused silica and crystal quartz products. For broad bandwidth applications, we use a longitudinal mode approach with a phased array of piezoelectric elements within the transducer. We achieve high efficiency with slow shear deflection using parallel tangents off-axis interaction. 2D UV beam scanning may be achieved by cascading two UV deflectors in series. Our flexible functionality Smart Dual Driver with phase synchronized outputs offers the optimum in RF driver control for 2D scanning. As high density material processing moves to smaller features written by shorter wavelengths, greater beam control is essential. Our deflectors meet these needs with highly accurate, repeatable positioning as well as rapid, agile, random access control for higher throughput.

Applications Digital imaging, heterodyne interferometry, laser cooling, laser marking, laser tweezers, material processing, micromachining, microscopy, on-line process control, optical inspection, photolithography, printing.

ACOUSTO-OPTICS

FREQUENCY SHIFTERS Dependable shift with high extinction ratio Like other acousto-optic devices, an acousto-optic frequency shifter (AOFS) Doppler-shifts the frequency of input light by an amount equal to the RF drive frequency, but is optimized specifically for this purpose. Typically our frequency shifters will use the anisotropic interaction of the slow shear mode in tellurium dioxide (TeO2). Applications such as interference-based optical techniques require a high extinction ratio between the diffracted and undiffracted beam; this can be achieved with a high-quality optical finish to minimize optical scatter. We offer standard products with frequency shifts of 40-350 MHz, many of which can be operated in double-pass configurations. In addition we can design for custom frequency shifts where required. Frequency shifters are fabricated using high quality TeO2, grown and polished in-house, for lowest insertion loss and excellent power handling. Other acousto-optic materials are available and may be more appropriate for some applications. TeO2 based frequency shifters are highly efficient acousto-optic devices, requiring very low drive power to achieve the desired frequency shift. Our designs consume minimal power (generally <100 mW power draw), often allowing us to package the driver with the AOFS for a more compact and power-efficient solution.

Applications Interferometry, laser cooling, laser Doppler velocimetry, laser Doppler vibrometry (LDV), optical heterodyne detection.

MODE LOCKERS For high power, high-Q mode locking of ultrafast laser pulses An acousto-optic mode locker (AOML) modulates the loss within a laser cavity at its resonant frequency, effectively “locking” the phase of the longitudinal modes to generate very narrow laser pulses of high intensity. G&H standing wave mode lockers yield near-theoretical mode locked laser pulse widths, with industry-leading transmission performance. Available in antireflection (AR) coated and Brewster angle options, they can also be customized for demanding one-off scientific and OEM applications. We combine extensive AO device design experience with strict manufacturing controls to deliver high-Q (very low loss) mode lockers with minimal extraneous modes, achieving picosecond and femtosecond length pulses at repetition rates of up to 200 MHz. To ensure high quality and reliability, our mode lockers use high quality fused silica, polished and fabricated in-house. Greater than 99% transmission at 1064 nm is achieved with our own durable antireflection V-coat. Transmission over a broader range of wavelengths (700-1100 nm) can be achieved using windows cut to the Brewster angle. Low scatter and tight quality controls ensure that every mode locker is capable of handling high peak laser power over the long term without damage. RF driver selection impacts mode locking system performance, as active temperature control of the acoustic resonator can assist in controlling resonant frequency such that resonance at the precise frequency of the driver’s oscillator can be maintained. G&H can assist in choosing the right driver for your application, advising on how performance of each RF driver will influence mode locking efficiency and pulse width.

Applications Femtosecond micromachining, fs/ps lasers (Nd:YAG, Nd:YLF, Ti:Sapphire, Argon ion), LIDAR, multiphoton microscopy, nonlinear optics, optical data storage, optical heterodyne detection for spectroscopy, telecommunications.

From custom wavelengths to high repetition rates, we offer a wide range of standard and custom options for high performance, high-reliability mode lockers to achieve the shortest, most intense pulses possible. PRODUCT CODE

ACOUSTO-OPTICS

MODULATORS Single frequency devices allowing intensity modulation of collimated light Acousto-optic modulators (AOM) allow the intensity of light to be controlled and modulated at rates that far exceed mechanical shutters. AOMs can be used like a shutter (cycling light on and off at a set frequency), or as a variable attenuator (controlling the intensity of transmitted light dynamically). The laser modulation is effected by means of RF interference induced sound waves in an acousto-optic crystal. G&H acousto-optic modulators are optimized for low scatter and high laser damage threshold, and can be matched to the rise time, modulation rate, beam diameter, and power handling needs of each application. Rise time is proportional to the time required for the acoustic wave to traverse the optical beam and for this reason is influenced by the beam diameter within the AOM. We offer very fast modulators with modulation frequencies up to ~80 MHz and rise time as low as 4 ns, requiring the input beam to be very tightly focused. Lower frequency modulators do not have this constraint, and can accept larger input beams. Their rise time is usually specified relative to the input beam diameter, in ns/mm. Our modulators typically achieve extinction ratios of >50 dB, usually with a deflected beam throughput of 85-90%. For applications such as intensity leveling where a lower contrast ratio of ~10 dB is acceptable, we offer modulators with >99% light throughput. Applications Heterodyne interferometry, intensity levelling, intensity modulation, laser cooling, laser Doppler velocimetry, laser Doppler vibrometry (LDV), laser linewidth measurements, LIDAR, marking, material processing, micromachining, printing, via drilling.

ACOUSTO-OPTICS

MULTI-CHANNEL MODULATORS Independent control of multiple beams or a sheet of collimated light Acousto-optic multi-channel modulators (AOMC) allow multiple beams to be modulated or deflected independently by integrating an array of transducers with a single acousto-optic crystal. Our proprietary optical and electrical designs minimize crosstalk, allowing concurrent operation of up to 48 channels for modulation and up to eight channels for beam deflection. Our AOMCs are known for their reliable operation and high performance. Multi-channel modulators have parallel beams as input, each beam independently controlled by a different transducer to modulate its intensity. Multi-channel modulators are most often used for high speed applications like micromachining and direct-write lithography, as each beam can be modulated independently. These devices can also be used to increase throughput when writing large media by writing multiple beams at the same time. Our multi-channel modulators equal the performance available with our single channel modulators, and can be customized for large aperture applications as well as high speed, small aperture applications. A multi-channel beam deflector however, generates multiple diffracted beams from a single input beam at specific locations by simultaneously applying multiple frequencies to a single transducer. Each individual channel is a deflector that can either scan the beam or produce multiple spots. This makes it possible to create a two-dimensional grid. For example, if a four channel beam deflector were configured so that each channel diffracted three spots, the result would be a 4x3 grid. High laser damage threshold is achieved using low-scatter materials. These are inspected to rigorous quality standards. We grow our own tellurium dioxide and source high quality fused silica and crystalline quartz to ensure low insertion loss and excellent optical power handling. Applications Marking, material processing, micromachining, printing.

ACOUSTO-OPTICS

PULSE PICKERS/CAVITY DUMPERS Rapid, synchronized pulse selection; internal or external to the laser cavity Pulse pickers and cavity dumpers are high speed acousto-optic modulators which separate and divert a single laser pulse within a pulse train to a new optical path. A cavity dumper is used inside the cavity of a mode locked laser, while a pulse picker describes the same function when used externally. Both use a high speed acousto-optic crystal and specialized design techniques to keep rise time to a minimum while operating at a low duty cycle to select individual laser pulses with speed and synchronization. Tight focusing of the beam within the device is required to achieve the desired speed (typically <0.1 mm), resulting in very high input power density. Our rigorous manufacturing standards and high crystal quality minimize scatter and enable industry-leading optical power handling. Antireflection (AR) coatings minimize insertion loss. By using a high RF carrier frequency and an optimized lens design, G&H pulse pickers and cavity dumpers provide large angular separation between the deflected and undeflected beams (up to 75 mrad). This makes it easy to separate the two beams in space and maintain a static contrast ratio of at least 500:1. The choice of RF driver is particularly important to achieve accurate synchronization with the laser pulse train. Controls on the driver optimize the RF drive pulse shape and delay. The modulation signal is synchronized and optimized using a control loop to select the best time at which to pick off the pulse. Applications Generation of high energy pulses, injection and extraction of pulses from regenerative amplifiers, femtosecond/picosecond lasers, reduction of pulse repetition rates.

ACOUSTO-OPTICS

Q-SWITCHES High power and low loss for lowering the cavity Q-factor and holding off lasing An acousto-optic Q‑switch (AOQS) works within a laser cavity to generate high intensity, short-pulse light by actively controlling the Q‑factor (loss) of the cavity. Our products are rugged, reliable, and long-lasting, backed by millions of hours of service in the field. We offer low insertion loss, highly efficient Q‑switches capable of handling very high peak power. We have off-the-shelf solutions for polarized or unpolarized lasers, and can accommodate large lamp-pumped multi-mode laser beam diameters as well as small, compact diode-pumped beam diameters. Specialized designs meet unique needs such as ultra-high single pass loss (up to 96%), high switching speeds, and premium pulse-to-pulse stability. Most AO Q-switch products utilize materials with high optical power handling such as fused silica or crystal quartz. In order to maintain high efficiency (i.e. loss modulation) with these materials, higher RF powers are necessary and therefore require adequate conduction or water cooling. All of our Q-switch products offer very low loss in the “off” state to maximize output intensity, and excellent transducer reliability to allow long-term use without maintenance. We also offer a full line of RF drivers designed specifically for Q‑switching, with rapid fall times, tight synchronization, operation in either fixed or variable mode, and advanced capabilities like first pulse suppression or multi-channel operation to drive multiple Q‑switches within the same cavity.

Applications Laser marking, lithography, material processing, medical surgery, micromachining.

The products listed below illustrate a range of typical G&H AOQS specifications. Products can be customized to meet the demands of specific applications.

ACOUSTO-OPTICS

TUNABLE FILTERS Precise, rapid wavelength selection and tuning An acousto-optic tunable filter (AOTF) is a solid-state, electronically-addressable random-access optical passband filter. It may be used to rapidly and dynamically select a specific wavelength from a broadband or multi-line source. When specific matching conditions between the acoustic and optical beams are met, diffraction will occur. As a result it is possible to electronically control key filter parameters such as wavelength, modulation-depth and even bandwidth, thus providing rapid (typically µs), dynamic, random access optical filtering. Resolution bandwidths down to <0.1% are available with exceptional performance and with aperture sizes up to 25 mm and beyond. We have developed and patented techniques to allow us to offer options such as large-aperture imaging filtering, sideband suppression, and transmission of multiple discrete wavelengths. G&H AOTFs are based on our in-house grown high quality tellurium dioxide polished and fabricated to rigorous standards.

Drive frequency [MHz]

We offer a range of AOTFs to suit a variety of applications. For scanning an entire image in wavelength at speeds sufficient for real-time video rate spectral imaging, high optical throughput is required. For this purpose devices with large aperture and/ or field of view are recommended. When narrow resolution is required and the light source is well collimated, a “quasi-collinear” AOTF may be more appropriate.

ACOUSTO-OPTICS

RF DRIVERS Stable, versatile electronic control options for acousto-optic devices An RF driver generates the fixed or variable frequency signal supplied to a device to induce the acousto-optic effect. The frequency and intensity of the applied signal will determine how much an optical beam is modulated, deflected, or tuned. An acousto-optic device and its RF driver should be selected as a unit to optimize speed and stability for each application. G&H offers a wide variety of stable high frequency drivers with analog and digital modulation capability, optimized by application with features such as first pulse suppression, synchronization, pulse shaping, and multi-channel operation. As our AO product lines expand, we are creating more flexible, adaptive drivers with dual analog/digital operation and configurable firmware to accommodate functionality like triggering and temperature control without the need for new hardware. Our OEM designs, in contrast, are optimized to each customer’s application, maximizing performance in the required form factor.

CHOOSING AN RF DRIVER The needs of the AO device dictate the choice of RF driver. Primary factors to consider are shown below, though speed, duty cycle, and special functions are also important. • • • • • •

RF power: ranges from <0.1 W to >150 W Modulation: digital or analog Frequency of operation: may be fixed, variable (linearly swept), or programmable Stability: influencing choice of VCO vs. DDS when frequency is not fixed Number of channels: number of output ports or output tones from a single port Special functions: pulse-killing, synchronization, etc.

Applications Driving and controlling acoustooptic devices: beam deflectors, cavity dumpers, frequency shifters, mode lockers, modulators (fibercoupled and free space), multichannel modulators, pulse pickers, Q-switches, tunable filters.

Modulation: Digital vs. Analog The modulation mode determines how the applied RF power is varied, and thus the intensity of diffracted light. In digital modulation, the RF power is applied in an on/ off state via an applied TTL signal, thus controlling whether the beam is diffracted. In analog modulation, the RF power is controlled through application of a voltage within a specified range, yielding control over the diffraction efficiency and allowing shaping of that waveform in time. Fixed vs. Variable Frequency Drivers Fixed frequency drivers provide a single output frequency which is matched to the AO device. Offered from 24-440 MHz, fixed frequency drivers may be controlled via analog or TTL input, some with manually adjustable output RF power. These are used most often for modulation applications. Variable and programmable frequency RF drivers allow active control of output frequency. Voltage controlled oscillators (VCOs) provide a linearly swept (variable) RF drive frequency, and are flexible enough to be used for any AO device. Direct digital synthesizer (DDS) drivers offer programmable frequency. They can create random waveforms from a single, fixed-frequency reference clock, and thus are ideal for pulse shaping and special functions. DDS drivers are software driven, and can be run from a user-friendly interface (a GUI), or controlled directly via computer driver commands. Our high-performance multi-frequency DDS drivers generate up to eight channels of RF frequencies simultaneously. Smart Drivers Smart drivers allow simple or complex digital waveforms to be synthesized, converted to analog signals, and amplified to drive the AO device. This gives great flexibility; for example, allowing the driver to provide multiple programmable frequencies or to swap freely between multiple, complex, customized waveforms. GOOCH & HOUSEGO

ACOUSTO-OPTICS

Frequency Agility and Control We manufacture Direct Digital Synthesizer (DDS) drivers that offer high stability and linearity, with fast switching time and high resolution. They are capable of creating arbitrary waveforms from a single, fixed-frequency reference clock, and thus are ideal for pulse shaping and special functions. DDS drivers can be run from a GUI or via driver commands in two modes: 1) random access, with digital words mapping to specific frequencies, and 2) chirped mode for continuous scanning in frequency increments. DDS drivers are also referred to as DFS (digital frequency synthesizer) drivers.

The products listed below illustrate a range of typical G&H AO device driver specifications. Our technical support team is available to advise on selection and optimization of RF drivers for specific applications, as well as customization of products for OEM integration.

TECHNICAL EXPERTISE AND MANUFACTURING CAPABILITIES G&H’s crystal growth capabilities extend over a significant number of materials; our crystals comprise the basis for many of our own products. Our experience growing lithium niobate (LiNbO3) dates back to 1967, when we produced the first commercially available material. Since that time we have constantly refined the growth and material processing to be able to produce the highest quality LiNbO3, providing the most consistent performance of acousto-optic and electro-optic devices such as modulators, Q-switches, Pockels cells. We also offer LiNbO3 as wafers, AR coated Pockels cell crystals with electrodes, and as periodically poled (PPLN) harmonic generators. Beginning with the raw chemicals, we grow, orient, fabricate, finish, coat, and mount ß-barium borate (BBO), cadmium sulfide (CdS), cadmium selenide (CdSe), potassium dihydrogen phosphate (KDP), and potassium dideuterium phosphate (KD*P) crystals in housings with apertures from 3 mm to larger than 300 mm. Additionally, we grow tellurium dioxide (TeO2) for our acousto-optic devices.

Laser manufacturers rely on us to provide the highest quality crystal optical components manufactured to specification. They benefit from our expertise with design recommendations to arrive at technically advanced, innovative, and cost effective solutions to meet the demanding requirements of modern laser systems and optical instrumentation. G&H customers include manufacturers and research laboratories that require the highest quality components for cutting edge applications. Large KDP and KD*P crystal plates grown, cut, and finished by G&H are in use at National Ignition Facility (NIF) and the Commissariat à l'énergie atomique et aux énergies alternatives (CEA).

Proprietary crystal growth optimization software enables us to supply custom crystal solutions for your project. We routinely produce crystals as large as 0.4x0.4 m for internal confinement fusion (ICF) applications, as well as crystals as small as a few mm in cross-section for microchip laser applications.

LITHIUM NIOBATE WAFERS High quality congruent and MgO doped wafers Lithium niobate (LiNbO3 or LN) is used in electro-optics, acousto-optics, nonlinear optics and guided-wave optics due to its attractive fundamental properties. These properties include wide transparency range, high electro-optic and nonlinear optic coefficients, very high electro-mechanical coupling coefficients, and chemical and mechanical stability. G&H offers X-axis and Z-axis orientation LN in congruent and 5.0 mol% magnesium doped compositions. We have refined our proprietary techniques for growth and processing to produce consistently high quality LN for one-off scientific and volume OEM applications.

Applications Isolators, low pass filters, ophthalmic surgery systems, use in Pockels cells, Q-switching, range-finders, target designators, waveguides, Wollaston prisms.

We provide congruent lithium niobate wafers for infrared light applications, and magnesium-doped periodically-poled LN (MgO:PPLN) for improved resistance to photorefractive damage at visible wavelengths. Our optical wafers undergo many stages of precision processing to ensure the highest quality is provided to the customer. Poling of the lithium niobate boules grown in-house aligns the ferroelectric domains along a single axis, after which the boule is shaped; slices are cut to within 6 minutes of the x- or z-axis with the assistance of X-ray orientation. A curved radius is ground on the outside edge of the wafer to reduce cracking and chipping, followed by lapping and chemical etching. Polishing of one or both sides brings the finish to within Ra <0.2 nm, and to a front surface quality of 10-5. We perform 100% visual inspection on finished wafers, and characterize stress and strain prior to packaging in a cleanroom environment.

PERIODICALLY-POLED LITHIUM NIOBATE High efficiency quasi phase-matching for OPO, SHG and DFG applications Periodically-poled lithium niobate (PPLN) nonlinear crystals are efficient wavelength converters from the visible region to 5 µm. By using lithography to define the poling pattern, it can easily be customized to a wide range of applications. Phase-matching over very long propagation lengths at infrared wavelengths is possible with our congruently grown undoped PPLN manufactured from highly uniform Z-axis wafers. Visible wavelengths are better served by magnesium-doped PPLN (MgO:PPLN), as the 5 mol% doping prevents photorefractive damage. Average powers of up to 1 W can be produced at 532 nm in our MgO:PPLN crystals without causing beam distortion. To achieve optimal conversion efficiency, the interacting waves need to be phasematched by choosing the proper poling period. Typical periods range from about 7 µm for second harmonic generation (SHG) producing 532 nm to around 30 µm for optical parametric oscillators (OPOs) pumped by Nd:YAG lasers. The poling is done in wafer form before the chip is cut and polished, allowing the configuration to be specifically tailored to each application. We can design fan-out gratings to allow continuous tuning as beam position is moved across the aperture, chips up to 80 mm in length to allow for maximum gain, and chips up to 40 mm in width to achieve fine tuning of the signal wavelength.

Applications Chemical fingerprinting, compact laser displays, countermeasures, difference frequency generation (DFG), laser cooling, laser display, microscopy, range-finding, second harmonic generation (SHG), sensing, target illumination, telecommunications, wavelength conversion.

Patterns with multiple gratings along the beam direction enable multiple nonlinear interactions in the same crystal. This can be used to increase the quantum efficiency of OPOs or to generate various different wavelengths at once. Chirped gratings are used to widen the wavelength acceptance or to compensate for group velocity walkoff in ultra-short pulses.

ELECTRO-OPTICS

TECHNICAL EXPERTISE AND MANUFACTURING CAPABILITIES G&H offers an extensive range of electro-optic devices based on potassium dihydrogen phosphate (KDP), potassium dideuterium phosphate (KD*P), ß-barium borate (BBO), and cadmium telluride (CdTe). Utilizing proprietary crystal growth, fabrication, and polishing techniques, we manufacture both longitudinal and transverse electrode configuration Pockels cells with clear aperture diameters ranging from 1.8 to 100 mm. Our unique KDP and KD*P crystal growth, Pockels cell design, and device manufacturing capacity allows us to support the needs of even the most demanding OEM or scientific laser system. The Commissariat à l'énergie atomique et aux énergies alternatives (CEA) and National Ignition Facility (NIF) both selected G&H as their primary supplier of large aperture Pockels cells for optical isolators in the high fluence lasers in their inertial confinement fusion programs. These laser systems are effectively the most powerful in existence and require extraordinarily low absorption KD*P. For high-average power and high repetition rate applications, we provide BBO Pockels cells, the preferred alternative to KD*P. The use of oxide based crystals and water-cooled designs allow for increased average power handling capacity. We offer CdTe devices for operation at longer wavelengths, which benefit from CdTe’s high electro-optic coefficient and non-hygroscopic nature.

Antireflective (AR) coating offerings for standard and custom wavelengths include dielectric anti-reflection coatings on fused silica windows for high laser damage threshold applications. High transmission solgel AR coatings on KD*P eliminate the need for index-matching fluid. Q-switches for high power lasers are based on lithium niobate (LiNbO3) grown in-house. LiNbO3 Q-switches provide low loss and high contrast ratio, and are preferred for rugged military and industrial applications.

DRIVERS G&H has also designed a range of Pockels cell drivers for these devices, suitable for incorporation into lasers and laser systems. The Q-Drive Q-switch driver is engineered for performance and durability, and is also available as a compact, packaged benchtop model or unpackaged for OEM integration. The R-Drive is available for regenerative amplifier requirements in an OEM or customizable design.

POCKELS CELLS Reliable Q-switching for high power and repetition rates Based on the Pockels effect, a Pockels cell alters the polarization state of light in an in an electro-optic crystal due to birefringence induced by an applied voltage. An optical switch can be created by adding polarizing elements to perform very rapid Q-switching of a laser. Drawing on proprietary crystal growth and fabrication techniques and decades of experience in electro-optic device design, G&H manufactures high quality longitudinal and transverse electrode configuration Pockels cells in ß-barium (BBO), cadmium telluride (CdTe), potassium dihydrogen phosphate (KDP) and potassium dideuterium phosphate (KD*P). Factors such as wavelength, average power, repetition rate, and aperture size determine the best material and design for each application.

KD*P POCKELS CELLS We offer small and large aperture model KD*P Pockels cells, generally used for applications under 10 kHz repetition rate. The highly popular and compact IMPACT series delivers reliable performance at high contrast ratios for OEM integration, while the CQX series packages the same performance in a larger footprint as a drop-in replacement for the QX series (already widely deployed in the field for decades). Devices in the large aperture TX series are designed for use as optical isolators, protecting beam lines in ultra-high power laser systems.

Polarization as Related to Applied Voltage

We recommend BBO Pockels cells for applications over 10 W average power and for repetition rates up to 600 kHz. Our low-loss designs employ transverse electric field geometry with dual crystals to minimize drive voltage, and are not subject to tracking degradation. Custom options include single crystal cells, longer cells requiring 50% less voltage, attenuated cells for applications requiring ultra-low piezoelectric response, and cells with water-cooled apertures for high average power operation.

POCKELS CELL DRIVERS Robust, compact packaged drivers for light switching applications The G&H series of Pockels cell drivers complement our full range of available Pockels cells, and are available in several configurations: benchtop drivers, unpackaged, or customized. High quality components are integrated into our short circuit proof designs to maximize lifetime, safety, and reliability, whether operating in commercial, military, or scientific Q-switched laser systems, or in regenerative amplifiers. When selecting a Pockels cell driver, it is important to know the required switching voltage, as it is typically higher for BBO than KD*P, and half-wave operation requires twice the voltage of quarter-wave. Our compact line of drivers achieve high typical switching voltages by applying opposing voltages to each lead (i.e., a high differential voltage). Switching speed and repetition rate also determine choice of driver.

Q-DRIVE FOR Q-SWITCHED LASERS The Q-Drive series offers a fast rise-time for KD*P Pockels cells used in Q-switched lasers with modest repetition rates. It has been designed for high noise immunity and optimum signal integrity, and can be placed close to the Pockels cell to minimize the output pulse rise time. A remote control connector allows convenient single-point access to all driver functions, with remote high voltage (HV) control and signal monitoring.

R-DRIVE FOR REGENERATIVE AMPLIFIERS The compact, cost-effective R-Drive series is designed specifically for use with BBO Pockels cells at quarter wave voltage. Offering both a fast rise and fall time, it allows laser pulses to be injected into or coupled out of an amplifier cavity quickly. Ideal for pulse selection and ultrafast laser regenerative amplifier designs up to 200 kHz, it can be incorporated into new systems or retrofitted as an upgrade to existing designs.

Fall time voltage across cell

OEM CUSTOMIZATION G&H Pockels cell drivers may be customized for each application, from wiring and signal interfaces to cooling by air, water, or conduction/convection. Options for enhanced reliability include complex voltage traces for the Q-Drive to avoid crystal degradation, and custom triggering logic with precisely controlled delays for the R-Drive MOSFETs to prevent damage in operation. All OEM designs are built to the desired form factor and mounting requirements. Applications Q-switching, regenerative amplifiers, laser pulse selection and management.

LITHIUM NIOBATE Q-SWITCHES Q-switching for rugged military and industrial applications An electro-optic Q-switch can be used to modulate the loss in a laser cavity at GHz switching speeds to generate high intensity, pulsed laser light. Q-switch lithium niobate (LiNbO3 or LN), crystals operate on the Pockels effect, altering the polarization state of light via electrically-induced birefringence. By placing the crystal between a pair of cross-polarizers, light can be passed or blocked at very fast switching speeds. G&H grows and polishes high quality lithium niobate crystals in-house for low wavefront distortion, applying electrodes for use in the transverse mode (i.e., electric field perpendicular to the optic or z-axis). Our LN crystals offer high extinction ratio, very low transmission loss, low switching voltage and temperature stability throughout a wide temperature range. High-performance antireflective (AR) coatings are applied to each face, reducing loss to ≤0.2% per surface while withstanding high optical power (500 MW/cm2 upon request). We have developed proprietary temperature-stable (TS and XTS) versions of our Q-switch products to allow operation over a wide range of temperatures while maintaining excellent contrast ratio. Typical lithium niobate Q-switches suffer from pyro-electric charge buildup at low temperatures, leading to premature lasing if radioactive americium is not used to ionize the air around the crystal and bleed off the charge. We use a proprietary thermo-chemical reduction technique to increase conductivity of our lithium niobate crystal faces, thus dissipating charge and eliminating the premature lasing effect. While this process increases insertion loss slightly, it allows our XTS series to be used in low-temperature environments such as aerospace. Applications Ophthalmic surgery systems, range-finders, target designators.

THE AWARD-WINNING FIBER-Q® Combining micro-optical packaging capabilities and acousto-optic expertise How G&H used its photonic packaging expertise to develop a much needed device for the fiber laser industry. Our R&D engineers took an innovative approach to the development of a laser modulation device for the fiber laser community. The resulting Fiber-Q® can be used to reproducibly switch a fiber laser, modulate the amplitude or frequency shift the wavelength with precise electronic control. G&H’s expertise in photonic packaging brought for the first time, the flexibility and reliability of acousto-optics to the fiber optic industry. The resulting compact, robust, low loss device can easily be incorporated into all-fiber laser architecture without compromising the key benefits offered by fiber based systems. The rapid adoption of fiber laser technology for material processing in manufacturing has led to massive advances in technology, enabling high performance, low cost manufacture of many of the products consumers take for granted today (e.g. smart phones and flat panel displays). Compared to other laser technologies used in materials processing, fiber lasers provide a lower cost, low maintenance, solid state solution.

Since its introduction in 2009, many fiber laser applications have come to rely on the Fiber-Q®: “The Fiber-Q® product developed by G&H is a critical component in our amplified systems. The fast-response afforded by acoustooptic technology makes for an ideal switching device, enabling us to pick pulses with an excellent extinction ratio from our mode-locked seed oscillators, which have pulse repetition rates in the order of 10s of MHz and no other solution provides the performance balanced with the practicality and cost. The stability of the fiber-coupled solution allows us to maintain the critical holistic "all-fiber" approach to building our fiber laser platforms, which, in turn, provides the cost, flexibility, and reliability benefits when compared to competing laser technologies.” John Clowes, Director of Business Development at Fianium.

Now available in wavelengths from 400-2000 nm, hermetic and non-hermetic versions and with three port versions offered as well as the standard two port. The list of situations in which the device is used continues to grow and now in addition to industrial laser materials processing now includes biomedical and sensing applications. Developed to service this market, Fiber-Q® can be easily integrated into any fiber laser system to modulate the laser output with stable high efficiency performance delivering superior machining effects. Providing fast switch speed, with high peak diffraction efficiency and reliable performance, it has become the first choice for most ultra-fast fiber laser system manufactures.

Gooch & Housego (Torquay) received the Institute of Physics Award for Innovation and in 2016, the Queen’s Award for Enterprise: Innovation. GOOCH & HOUSEGO

The Fiber-Q® story illustrates how G&H is able to take one its core areas of expertise – in this case acousto-optics – and combine it with its micro-optical packaging capabilities to produce a world class, market leading device.

DFB LASER MODULES Building upon our proven 14-pin packaged DFB lasers, G&H also offers compact OEM modules with excellent linewidth performance. All G&H modules comprise an integrated DFB laser, low noise diode driver, and TEC controller. To operate, the user need only provide a simple 5V power supply and voltage based tuning signals for temperature or current (chirp) adjustment, if required. The incorporation of an ultralow noise current source for the diode offers a vastly improved linewidth. The EM650 typically provides linewidth in the range of 100-350 kHz in a handsized package, approximately 66x64 mm (2.5”x2.5”) in size. The EM750 features an additional external cavity in a slightly larger package (3”x5”) to reduce the linewidth to approximately 10 kHz while emitting up to 50 mW out of the fiber. The expanded high bandwidth series of integrated modules includes two compact, easy to use models with direct modulation speeds in excess of 12 GHz. The EM655 offers the lowest linewidth at 1 MHz. The EM657 features an integrated internal switching power supply to remove the inherent voltage potential on the RF connector that is typically associated with laser diodes. The tuning port capacitive load on the EM657 is also lower, allowing for easier control via digital to analog converters.

HIGH SPEED DETECTORS Ripple free, linear response from DC to 20 GHz High speed detectors (HSDs) are a crucial component at the interface between optical and electrical communications systems to achieve clean conversion of photonic RF signals to electrical RF signals at high bandwidth and fidelity. Our photodetector designs offer low dark current or noise, and perform with excellent responsivity. The EM169 photodetector series offers bandwidth rated to a minimum of 20 GHz over multiple wavelength bands with a single device, including 1310 nm, C-band, and L-band. The new EM530 photodetector further expands the product range with a dramatic increase in power handling over the same broad wavelength range, and features a bandwidth of 10 GHz. For a 50 mW input signal, the EM530 photodetector provides a 32 mA photocurrent level, thus increasing the level by a factor of 10 compared to the EM169 and other comparable photodetectors. Manufactured in volume, G&H’s two high speed photodetector devices are rated for performance over a wide temperature range. Our designs maximize photodetector performance to enable higher power and high speed ruggedized systems for defense and other demanding applications.

LASER CONTROLLERS Convenient USB or touch-pad interface control of diode lasers Benchtop laser controllers provide a convenient interface for operation of diode lasers in production or laboratory environments. Our easy-to-use controller is compatible with single-mode (SM) and DFB lasers in standard 14-pin butterfly packages, allowing simple touch-pad or computer control of interchangeable lasers with different wavelength or power characteristics. The EM595 benchtop controller combines a laser driver and thermoelectric cooler (TEC) controller into a compact, benchtop device with an intuitive user interface. With 1.5 A of laser drive current available, the G&H EM595 laser diode driver can operate any 14-pin DFB or single-mode laser. The 3.0 A of current available for the TEC provides ample controlling capability for typical room or lab temperature environments, with the capability of operating single mode (SM) or distributed feedback (DFB) lasers over their full rated range. Precise temperature control results in accurate laser frequency control. The EM595 establishes a new level of low noise and linewidth performance in a benchtop device. The ability to easily swap lasers with different wavelength or power characteristics allows a single controller to operate several lasers. This is useful for experiments involving repetitive testing where users need to dynamically modify operational parameters to meet test objectives. In production environments, the benchtop EM595 unit allows quick and easy testing and verification of a variety of products flowing through a production line. The automation offered by our laser diode driver further saves time and money while maintaining quality, calibrated results. Applications Laboratory and production testing.

FIBER OPTICS

FUSED FIBER OPTIC COMPONENTS The highest performance fused fiber couplers and high power combiners G&H manufactures a comprehensive line of optical taps, power combiners, attenuators, and WDMs based on fused fiber technology for wavelengths from the visible through near-infrared. Fused fiber couplers split and combine light signals by coupling light directly between the fiber cores, offering advantages in efficiency and reliability over filterbased couplers. By varying the parameters of the fusion and tapering process, our components precisely control the proportion of light split between fibers and the wavelength at which the split occurs. G&H fused fiber components are used for branching of optical signals and interfacing in telecommunications, sensor, and biomedical systems. We also offer devices to meet the needs of optical coherence tomography (OCT) based systems, and components for operation over a broad band centered at 2 µm. Our fused coupler production process has been honed over decades to achieve low insertion loss, high power handling, and high extinction ratio, with exacting manufacturing controls to ensure high quality and reliability.

SINGLE-MODE FIBER COMPONENTS G&H single-mode couplers are used to achieve accurate monitoring and splitting of optical signals from 1% to 50%. Polarization-maintaining (PM) couplers are available in slow axis, fast axis, and axis-independent variants. PRODUCT

HIGH RELIABILITY FUSED FIBER OPTIC COMPONENTS Proven performance and reliability for undersea and space applications The G&H line of HI REL components are deployed in environments such as undersea and space where the costs of component replacement are prohibitive and reliability is of premier concern. G&H is established as a preferred supplier of these components to most major undersea telecommunications equipment manufacturers. Our HI REL capability is built upon the foundation of an extended history of also manufacturing very reliable components for land-based (or terrestrial) systems in volume. G&H has established full reliability testing facilities to carry out customer specific HI REL qualification programs, which can include accelerated aging and Weibull analysis. Failure rates for undersea telecommunication systems and components are often described using a FIT rate (Failures in Time). The fused fiber couplers from our HI REL coupler range offer a very low 0.1 FIT rate, equivalent to one failure in roughly fifty thousand components in 25 years. The ultra-low loss of G&H fused fiber components helps to promote low noise figure and improved system margin in undersea transmission systems. Components are supplied in regular (bare fiber), semi-ruggedized (0.9 mm sleeving) or custom housings, depending on the installation environment. The newest addition to the range is our pump combiner, which allows erbium-doped fiber amplifier (EDFA) designers to double pump powers. This enables higher power EDFAs and in turn greater data carrying capacity. In space applications, photonics is expected to displace current RF/microwave satellite technology for transport of data between satellites, and between satellites and the Earth. In addition to offering higher data carrying capacity than the present radio wave systems, the reduced size and weight of optical systems will enable smaller, lighter next generation satellites. The G&H HI REL space range of fused fiber components builds on the quality and reliability for which our undersea couplers are known, adding features such as material lot unicity, qualification in high radiation environments and lot validation testing. Services for HI REL customers include custom qualification programs, dedicated workstations, full traceability of materials and processing, advanced fiber management, and customer-specific validation tests.

Its high tensile strength makes it well suited to many high g-force environments. In addition, sapphire is very tolerant of high radiation environments, such as space-based applications. Due to its high mechanical strength, sapphire is a very difficult material to polish. Our unique superpolishing processes allow us to polish sapphire components to better than 1 Å surface roughness. Silicon Carbide Silicon carbide (SiC) is often used in the optics industry to replace components previously manufactured from beryllium. The material offers a viable alternative with low weight, high specific stiffness, high thermal conductivity and excellent dimensional stability. We have developed expertise in polishing silicon carbide mirrors, and can polish CVD SILICON CARBIDE™ and lightweighted versions of this material. G&H also offers customer-supplied substrate polishing services. Additionally, we offer SiC cladding with IBS coatings to ensure the finest possible final surface finish. Lastly, we also supply optical coatings on the finished mirror.

COATINGS G&H operates four facilities with thin film optical coating capabilities: two in the US and two in the UK; each with multiple chambers. We offer customers temperature stable optical coatings to meet high laser damage thresholds at short pulse lengths across the bandwidth of commercial laser wavelengths from deep UV through to far IR. Our expertise in coating has been supported by investment in custom built, ultra-clean, high repeatability chambers to meet customers’ evolving needs for environmentally-stable optical coatings. Our engineers are continuously researching the performance characteristics of new coating materials and integrating the results into our modelling software to optimize the designs for customers’ applications. We have a comprehensive range of coating techniques: • • • • •

Thermal evaporation Electron-beam (e-beam) Ion assisted deposition (IAD) Ion beam sputtering (IBS) and Chemical vapor for diamond-like coatings (DLC)

A chamber that incorporates thermal, e-beam, and an ion source provides increased coating flexibility. This enables us to tune and allow selective bombardment of the various coating materials during deposition to match challenging substrate types and meet exacting performance requirements.

PRECISION OPTICS

We use thermal evaporation for deposition of metals and dielectrics which are less compatible with e-beam coating. For the many materials that are compatible however, the e-beam technique provides coating with lower stress where surface flatness is a priority, higher laser induced damage threshold (LIDT), and improved control of impurities in the deposited material. E-beam is especially useful for coating components for operation at deep ultraviolet and infrared wavelengths. Ion assisted electron beam (IAD) coating deposits robust coatings with very high laser induced damage threshold (LIDT) and very low thermal shift. IAD coatings are widely utilized for optical systems designed for the defense industry where multiple laser wavelength devices are required to work together in rugged environments.

Ion beam sputtering (IBS) generates very dense, hard coatings ideal for very high reflection and low loss requirements. IBS is thus well-suited to finishing super-polished mirrors – whether for cutting edge research or for Ring Laser Gyros (RLG). IBS coatings have a lower LIDT than IAD coatings. As part of the quality control process, we test our coated optics using the following processes: • •

HY-PER BOND™ – ADHESIVE AND ORGANIC-FREE BONDING Hy-Per Bond™, our adhesive-free bonding process, overcomes issues such as beam distortion and performance degradation resulting from the outgassing of optical cement. Hy-Per Bond™ is more tolerant of temperature differentials than optical contacting when used in high energy, humid, or cryogenic applications. By activating precision optical surfaces prior to joining them, permanent bonds are formed between the components, improving environmental stability. When bonding low expansion ceramics, thermal distortion is negligible. Key features include: • • • • • • • • • 60

Space qualified No outgassing In shear strength trials the bulk material fails, rather than the bond Negligible thermal distortion Resistant to moisture and vibration Maintains strength at cryogenic temperatures Stronger than optical cement (>50 MPa) Alignment at submicron accuracy Bond thickness ~100 nm

Hy-Per Bond™ is suitable for a wide range of materials, including fused silica, ZERODUR®, crystal quartz, and optical glasses. Hy-Per Bond™ can also be utilized for large surface areas, up to 170 cm2. Bonds tested achieved a laser induced damage threshold (LIDT) of >15 J/cm2, significantly better than typical epoxy-based bonds.

PRECISION OPTICS

PRECISION PRISMS Precision in every facet for challenging applications The simplicity of the prism function belies the complexity of its manufacture. Each surface that is polished and coated must also be held in the strictest of angular tolerance to the other surfaces. Prisms bend, fold, invert, reinvert, displace, and deviate light. Though not used as often as lenses and mirrors, prisms are critical components in the systems which utilize their bending or refracting properties. Prisms are challenging to fabricate as each surface and its angular tolerances to the whole are difficult to maintain during polishing and coating. Prism manufacturing requires complex tooling as difficult to manufacture and maintain as the prism itself. In order to collapse or control the optical path, optical engineers may generate designs which require optical contacting of multiple prisms to create complex optical structures. Each angle and surface must be held in the tightest of tolerances to the whole piece. Coatings are similarly difficult, as surfaces may receive different coatings, fixturing is complex, and the final surfaces may need to be completely flat to enable proper contacting, bonding, and alignment to the whole assembly. Prisms types include: Abbe, Amici, Dove, Leman, Penta, Periscope, Porro, Rhomboid, Schmidt, Wollaston and Zeiss. We invest in state-of-the-art metrology to ensure customers receive the highest quality products. G&H has received ISO9001 certification across all of its manufacturing sites and AS9100C certification has been achieved at select facilities. Durability testing can be performed against MIL, DIN, or BSI standards as appropriate.

CORNER CUBES Circulators for laser cavities Our high laser damage threshold corner cubes are used in laser range finders to collapse the optical cavity, reduce weight, and improve system performance. Corner cubes comprise three mirrors, or reflective prism faces, which return an incident light beam in the opposite direction. Corner cubes are primarily used in either imaging or laser applications.

IMAGING Corner cubes for imaging applications are used where it is difficult or too timeconsuming to attain precision alignment of the returned beam. The monolithic structure of the component eliminates mounting errors which can arise when using mirrors and is also less sensitive to thermal errors. Such corner cubes are optimized for broadband performance and minimal transmitted wavefront distortion. Corner cubes may be supplied with or without coatings on the reflecting surfaces as they operate on the principles of total internal reflection (TIR). Coatings are recommended in applications where TIR angles are exceeded or the surfaces cannot be kept clean.

LASER CAVITIES Corner cubes from G&H are most often used in laser cavity designs as a circulator.

PLATE AND CUBE BEAMSPLITTERS Accurate solutions for high energy applications Optimized beamsplitter designs from G&H demonstrate superior laser damage performance for each unique wavelength, split, and incident angle combination. Cube beamsplitters can divide the incident beam based on polarization (S or P) or power (ratio of energy into each arm). They are easy to mount and mechanically durable. Cube beamsplitters from G&H may be provided cemented, optically contacted, or even air-spaced. For some applications, higher power handling and lighter weight is required. Plate beamsplitters display intrinsically higher beam power handling capability than cube beamsplitters. Plate varieties are preferred in high laser energy applications, or where cost or weight limits on the assembly come into play. However, the physics of the plate beamsplitter operation generates a beam offset dependent upon the thickness of the substrate. An anti-reflection coating on the exit surface of the substrate can minimize the ghost beam.

Cube beamsplitters are durable and minimize ghost beams

Beamsplitter types and selection factors Selection of the appropriate beamsplitter design is dependent upon several factors: • • • • • • •

WINDOWS AND OPTICAL FLATS Custom solutions for environmentally challenging conditions Optical windows are a critical component in a variety of applications which require minimal optical impact with maximum mechanical separation between two environments.

WINDOWS FOR INDUSTRIAL APPLICATIONS Optical windows are utilized in lasers, testing chambers, and other systems where the environment on one side may be pressurized, filled with a specific gas, or otherwise need to be chemically separated from the other. The window needs to transmit the photon energy with minimal disruption (highest transmission, lowest absorption and scattering, and minimal polarization or optical path distortion). Highest quality optical windows from G&H demonstrate very high parallelism, supremely low surface roughness, low transmitted and reflected wavefront errors, and are optical transparent at the operational wavelength range. Window material is chosen based on environmental factors such as acidity of atmosphere, strong vacuums, high pressures, or high temperatures and the operational wavelength range.

WINDOWS FOR DEFENSE APPLICATIONS Defense-grade windows from G&H are significantly larger and may be coated with diamond-like coatings to withstand abrasive environments in the desert. Window thickness is determined by environmental factors: pressure differentials, thermal conditions, and mounting mechanics. G&H has received ISO9001 certification across all of its manufacturing sites and AS9100C certification has been achieved at select facilities.

WAVEPLATES Superior polarization control across the spectrum From crystal growth, crystal orientation and cutting, to waveplate fabrication and coating, no other waveplate supplier has as much control over the fabrication stages as G&H. For all wavelength ranges, we orient, cut, and polish the optical crystals for waveplate production. Tight internal controls enable better retardation tolerances within and between production runs. Polishing, coating, assembly, and metrology complete the manufacturing process. Compound zero-order (also known as net-zero order) and achromatic waveplates are often optically contacted to reduce reflection losses at the surfaces. Air-spacing is recommended for high energy applications. Specialty waveplate designs such as offaxis or true-zero order waveplates are produced to custom specifications.

PRECISION OPTICS

SUPERPOLISHED SROC High quality superpolished short radius of curvature optics Gooch & Housego has been producing superpolished surfaces for over 40 years and is the world’s original provider of superpolished optical components. We have evolved our proprietary process to handle high volume and specialized R&D requirements. Superpolished substrates feature surface roughness lower than 1 Å, scratch-dig <5-2, and inspection upwards of 320x magnification. The result is extremely low scatter, losses and defects – a requirement for any high performance laser application. The substrates offer an impressive λ/20 or better surface accuracy. In keeping with the high standards of our superpolished surfaces, most of our optics are supplied with polished or acid etched diameters or bevels. These extra touches add to the level of cleanliness and durability that can be achieved. To complement our superpolished surfaces we offer ion beam sputtered (IBS) coatings which achieve very low levels of total loss (absorption and scatter), and exceptional environmental stability. G&H has received IS09001 certification across all of its manufacturing sites and AS9100C certification has been achieved at select facilities. Applications Cavity enhanced absorption spectroscopy, ring laser gyroscopic systems, ultrafast laser research, ultraviolet laser systems.

RING LASER GYROSCOPE COMPONENTS Delivering precision and complexity for navigation-critical components Vertical integration enables G&H to supply the entire ring laser gyroscope (RLG) package: RLG frame and optical components. Our integration of capabilities delivers superior performance and streamlines sourcing. There are many components within the ring laser gyroscope; each performs unique functions and is optimized accordingly. The Zerodur® frame must deliver maximal stability over a large range of operating environments (namely, temperature, humidity, and environmental composition). We have 40 years of experience producing high-quality, consistent, Zerodur® frames. Flat, wedged, and curved mirrors used in RLGs are superpolished with surface roughness better than 1 Å RMS with high-reflectivity low-loss IBS coatings designed to survive extreme environmental conditions.

INFRARED OPTICS Integrated fabrication capabilities Our combination of technical skills, manufacturing competencies, and metrology capabilities enable G&H to deliver highly integrated, superior performing optical components. G&H brings together a set of capabilities which enable our customers to combine techniques, even on the same part. G&H utilizes several techniques (high precision CNC processing, diamond turning, magnetorheological finishing, and traditional polishing) either separately or in tandem to achieve superior product specifications, such as surface accuracies to better than 100 nm. One of our distinguishing capabilities is our ability to manufacture complex shapes on lenses, such as step profiles or off-axis shapes. Durable antireflection (AR) coatings from G&H are tailored to the application. Typical AR coatings include: Broadband, V-coat, and dual band. Broadband coatings perform well from 400-14000 nm wavelength ranges. Reflectivity as low as 0.25% for the 3-5 μm range is achievable. Extensive metrology capabilities are critical to the abilities of G&H to meet and exceed difficult specifications. •

OPTICAL DOMES IR domes for aerospace and defense

NEW

CNC processing, combined with extensive metrology capabilities, deliver precision domes for aerospace and military applications. Optical domes are essentially windows: two parallel surfaces, curved. The dome protects and isolates critical sensors and electronics from the environment with minimal disruption to the optical path. High numerical aperture (NA) optical domes from G&H are produced using precision tooling. This new capability features zinc selenide, zinc sulphide, or germanium materials. To ensure performance in the field, we leverage our extensive metrology capabilities to qualify every component at every step in the manufacturing process. Optical domes are difficult to measure; therefore, we have developed proprietary stitching interferometry processes to minimize errors due to reflections. Environmental testing of components and coatings is critical for assurance of performance in rugged conditions. Environmental testing capabilities include MILC-675C, MIL-C-48497A, MIL-E-12397, and MIL-M-13508C for endurance against abrasion, adhesion, humidity, temperature, and environmental conditions. G&H has received IS09001 certification across all of its manufacturing sites and AS9100C certification has been achieved at select facilities.
