Wavelength 415-1550 nm; Type Visible, IR; Operating Frequency 40-200 MHz; Active Aperture 1.5-6 mm; Optical Material Tellurium Dioxide Transmission through an acousto-optic (AO) device causes the input light to experience a frequency shift equal to the RF drive frequency. The acousto-optic frequency shifters (AOFS) from Gooch & Housego (G&H) are optimized for the needs of applications like interferometry, with the ability to achieve high extinction ratio between modes.The product line includes standard products with frequency shifts of over 300 MHz and integrated low-power AOFS modules in which the RF driver has been built into the housing. Frequency shifters for specific application, including frequency shifts up to 600 MHz, can be customized on request. The frequency shifters are manufactured using high quality tellurium dioxide (TeO2), grown and polished in-house, for lowest insertion loss and excellent power handling. Standard AOFS products are offered for wavelengths in the visible and NIR for use with fundamental and doubled Argon Ion, Nd:YAG, He:Ne, diode, dye, and Ti:Sapphire lasers. With standard frequency shifts of over 300 MHz and custom frequency shifts up to 600 MHz, as well as models for double-pass configurations, the frequency shifters match most research and industrial needs. Frequency shifters are highly efficient acousto-optic devices, requiring very low drive power to achieve the desired frequency shift. G&H’s AOFS designs typically use the slow shear mode, resulting in slow rise time, but requiring minimal power consumption (typically < 100 mW power draw). This allows to often package the driver with the AOFS for a compact and power-efficient solution.

Gooch & Housego’s mode lockers for Nd:YAG, Nd:YLF, Ti:Sapphire and Argon Ion lasers can modulate at up to 200 MHz, yielding near-theoretical mode locked laser pulse widths. Antireflection (AR) coated and Brewster angle options are available. Customized one-off mode lockers can be designed for demanding scientific and OEM applications.The acousto-optic mode lockers from Gooch & Housego are manufactured using high quality fused silica, polished and fabricated in-house to ensure high quality and reliability. >99% transmission at 1064 nm is achieved by using a durable in-house antireflection V-coat. 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. The standard mode lockers include operating frequencies from 38 MHz to 80 MHz. The more modes are locked together in phase, the shorter the pulse. G&H’s standing wave mode lockers can obtain near theoretical mode locked laser pulse widths, with industry-leading transmission performance. The high-Q mode lockers can be used for Nd:YAG, Nd:YLF, Ti:Sapphire and Argon ion lasers at near infrared wavelengths to achieve picosecond and femtosecond length pulses at repetition rates of up to 200 MHz. The short pulses generated are often used in applications like nonlinear optics, optical data storage, femtosecond micromachining and multiphoton microscopy. High repetition rates are often desired for scientific applications, including those using optical heterodyne detection for spectroscopy, LIDAR or telecommunications. RF driver selection impacts mode locking system performance. 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.

The AO modulators available from Gooch & Housego (G&H) are optimized for low scatter and high laser damage threshold. Rise time, modulation rate, beam diameter and power handling requirements of the application need to be understood in order to identify the best acousto-optic modulator and RF driver solution.An acousto-optic modulator (AOM) uses sound waves within a crystal to create a diffraction grating. As the power of the applied RF signal is varied, the amount of diffracted light varies proportionally. Modulators 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).Contact our sales team to identify the best RF driver for your specific applicationApplications: 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 Series Wavelength Rise / Fall Time Active Aperture Operating Frequency Optical Material Type Downloads I-M0XX-XC11B76-P5-GH105 5.5 µm 120 ns/mm up to 9.6 mm 40.68 - 60 MHz Germanium N/A Datasheet Driver   I-M050-10C11V41-P3-GH75 9.4 µm 120 ns/mm up to 9.6 mm 40/60 MHz Germanium Mid-IR Datasheet Driver   I-M041-XXC11XXX-P5-GH77 10.6 µm, 9.4 µm 120 ns/mm up to 9.6 mm 40.68 MHz Germanium Mid-IR Datasheet Driver   AOMO 3200-1220 257 nm 10 ns 0.25 mm 200 MHz Crystalline Quartz UV Datasheet Driver   I-M110-3C10BB-3-GH27 AOM 300 - 400 nm 113 ns/mm 3 mm 110 MHz Crystalline Quartz UV Datasheet Driver   I-M110-2C10B6-3-GH26 AOM 400 - 540 nm 113 ns/mm 2 mm 110 MHz Crystalline Quartz Visible Datasheet Driver   AOMO 3080-125 415 - 900 nm 25 ns 2 mm 80 MHz Tellurium Dioxide Visible Datasheet Driver Driver AOMO 3080-120 440 - 850 nm 34 ns 1 mm 80 MHz Tellurium Dioxide Visible Datasheet Driver   AOMO 3110-120 440 - 850 nm 18 ns 0.6 mm 110 MHz Tellurium Dioxide Visible Datasheet Driver   AOMO 3100-125 440 - 850 nm 160 ns 1.5 mm 100 MHz Tellurium Dioxide Visible Datasheet Driver Driver AOMO 3110-121 442 - 488 nm 18 ns 0.6 mm 110 MHz Tellurium Dioxide Visible Datasheet Driver   AOMO 3200-120 442 - 488 nm 13 ns 0.45 mm 200 MHz Tellurium Dioxide Visible Datasheet Driver   AOMO 3200-121 442 - 488 nm 18 ns 0.32 nm 200 MHz Tellurium Dioxide Visible Datasheet Driver   AOMO 3200-125 470 - 690 nm 160 ns 1.5 mm 200 MHz Tellurium Dioxide Visible Datasheet Driver Driver AOMO 3200-124 780 - 850 nm 10 ns 0.32 mm 200 MHz Tellurium Dioxide IR Datasheet Driver   AOMO 3080-122 780 - 850 nm 25 ns 1 mm 80 MHz Tellurium Dioxide IR Datasheet Driver   AOMO 3200-1113 870 - 1250 nm 10 ns 0.1 mm 200 MHz Tellurium Dioxide IR Datasheet Driver   I-M041-2.5C10G-4-GH50 AOM 1030 - 1064 nm 113 ns/mm 2.5 mm 40.68 MHz Crystalline Quartz IR Datasheet Driver   I-M080-2C10G-4-AM3 AOM 1030 - 1064 nm 113 ns/mm 2 mm 80 MHz Crystalline Quartz IR Datasheet Driver   AOMO 3110-197 1030 - 1090 nm 18 ns 1.25 mm 110 MHz Tellurium Dioxide IR Datasheet Driver

The AO multi-channel modulators manufactured by Gooch & Housego (G&H) feature reliable operation and high performance with minimized crosstalk thanks to proprietary optical and electrical designs to allow concurrent operation of up to 48 channels for modulation, and up to 8 channels for beam deflection. Multi-channel modulators are most often used for high speed applications like micromachining and direct-write lithography, as each beam can be modulated independently. They are also used to increase throughput when writing large media by writing multiple beams at the same time. A typical multi-channel modulator has parallel beams as input, each operated on by a different transducer to modulate its intensity. Available models have 2 to 48 channels for UV through NIR wavelengths, with rise times as short as 7 ns for apertures < 1 mm. Multi-channel RF drivers are available with analog or digital modulation.High laser damage threshold is achieved using low-scatter materials inspected to rigorous quality standards.

Gooch & Housego’s (G&H) Fiber-Q® modulators offer high extinction ratio, low insertion loss and excellent stability in both polarization maintaining (PM) and non-PM formats at modulation frequencies up to 80 MHz for visible and infrared wavelengths. Built for reliability, the Fiber-Q® series of products features a rugged hermetic design in a compact, low-profile package, ideal for ease of integration into all-fiber and OEM systems, including medical laser systems.Each Fiber-Q® acousto-optic modulator requires an RF driver to generate the RF signal creating the acoustic wave within the embedded AO crystal. Modulation of the beam through the Fiber-Q will depend upon the frequency and intensity of the applied RF signal. Contact our sales team to identify the best RF driver for your specific application, taking into consideration the type of modulation required (digital or analog) as well as any specific pulse shaping needs.A fiber-coupled acousto-optic modulator (FCAOM) can directly control the temporal characteristics of the active output from a fiber laser, offering a wider variety of pulse shapes. As a byproduct of the acousto-optic effect, light passing through the first order diffraction mode of a fiber-coupled modulator also experiences a frequency shift and beam deflection. This allows the Fiber-Q® products to be used for more than just modulation, resulting in applications outside the laser such as optical heterodyne interferometry. G&H’s fiber optic acousto-optic modulators are designed for low insertion loss, high extinction ratio and excellent return loss. Typical optical performance for the Fiber-Q® series includes: Insertion loss: as low as 2 dB, depending on model Extinction ratio: 50 dB Return loss: 40 dB Polarization extinction ratio: 20 dB (for polarization-maintaining models) G&H has developed the first devices for visible wavelengths from 397 nm to 780 nm to meet the needs of sensing and quantum technology applications.

Locking Accuracy 1°; Bias Voltage -10-10 V; Pilot Tone Frequency 9.8 kHz; Dimensions 45.7x20.3x12.7 mm OZ Optics’ MBC-CHIP chip-size modulator bias controller is a single-function, chip-size, OEM version of the MBC family of modulator bias controllers. It is designed especially for digital system applications. The small size of the board makes it easy to be integrated into the system. This chip-size MBC is designed to lock the working point of the modulator at positive slope quadrature (quad+), negative slope quadrature (quad-), null or peak points of its characteristic curve respectively. The locking mode and slope has to be specified before ordering. The Chip size MBC is designed to use the built-in PD of the modulator but the user may also use an external PD by soldering it to the MBC-Chip. Key Features: Single-function Unit With Q+/Q-, Null/Peak Options Low Profile: 45.7 x 20.3 x 12.7 mm Access for External Photodetector Input Signal Current: 0.8 µA to 80 µA Locking Accuracy: 1° Typ., 3° Max.

The MBC-DBC ditherless modulator bias controller locks the bias of the device to the desired reference point. It has many applications, such as for MZ Modulator Bias Control or for Fabry-Perot filter control. Since it does not apply pilot tones, it does not disturb the system, which is very important for many analog systems. The MBC-DBC ditherless modulator bias controller features high accuracy and high dynamic range. The locking slope can be switched with a sliding switch on the board as long as the working function of the device is periodical. When the drift is out of the specified range, the unit will pull the bias back to the desired working point close to 0 V. There are two photodiodes built into the board. An external reference voltage can also be applied if specified at the time of order. OZ optics’ MBC-PDBC precision ditherless bias controller’s most important feature is its use of pilot tone mode to accurately bring the modulator to the Quad position, followed by the use of ditherless mode to continue locking the modulator at that point. The user can also disable the pilot tone and use the manual mode to lock the bias of the modulator or the device under control to another desired working point. The locking slope can be switched with a jumper on the board. When the modulator drifts out of the specified range, the unit will pull the bias back to the desired working point. There are two built-in photodiodes on the board. An external reference voltage can also be applied when specified at the time of order.

Null Mode Extinction Ratio 30 dB; Dimensions 41x77.5x16.5 mm OZ Optics’ MBC-HER high extinction ratio, full-function, miniature OEM version modulator bias controller is designed to be used with a single MZ modulator for high extinction ratio applications. The MBC modulator bias controller not only can be used to lock the working point of the modulator at the positive slope quadrature (quad+), negative slope quadrature (quad-), null or peak points of its characteristic curve, but also features an extremely small pilot tone which allows for an exceptionally high extinction ratio of >45 dB, depending on the limits of the modulator. The locking modes and slopes are selectable by changing the jumper positions on the PCB. A pigtailed photodetector is included. An external photodetector may also be used.

1000-1650 nm; Board Style; Detector Input Power -25--10 dBm; Differential Bias Voltage -25-25 V; Single End Bias Voltage -12.5-12.5 V; Typ. Null Mode Extinction Ratio 25 dB; Dimensions 90.7x85.6x16.5 mm OZ Optics’ MPC-QPSK DP and SP QPSK-modulator bias controllers are devices specially designed to control the bias positions for QPSK-modulators used for 100 Gbit QPSK or QAM applications. DQPSK (Differential Quadrature Phase-Shift Key) modulators can improve optical transmission properties such as total reach, dispersion tolerance, or spectral efficiency. Since the QPSK modulators are a combination of 2 phase modulators and 4 Mach-Zehnder modulators, there are six bias points requiring control. OZ Optics' QPSK modulator bias controllers have been developed especially for this kind of device. The OZ Optics QPSK modulator bias controllers are full-function miniature OEM versions of the MBC family of modulator bias controllers. They simultaneously set the first and second modulators of each QPSK modulator at Null points and set the third modulator of each QPSK modulator at the quad point. The slope of each point is selectable from the computer. The pin-out of the connector of the MBC is made according to the OIF-2009 specification. The DP-QPSK modulator can be directly plugged into the connector. The 18 low-speed device’s pins are grouped in groups of 6 pins. Key Features: Six Modulators Can Be Controlled by One Controller (1st, 2nd Modulator of Each QPSK Modulator at Null/Peak Mode, the 3rd at Quad) User-selectable Locking Slope (NULL <-> PEAK) Through USB Interface One Photodiode is Integrated in the Controller Both Single-ended and Differential Bias Outputs Three Operation modes: DQPSK, QAM or Arbitrary-waveform All Settings are Remotely Controllable Through USB Computer Interface, or UART User Can Select Automation Mode or Manual Mode User May Stop the Pilot Tone for Any or All Modulators and Manually Tune the Bias Through USB Computer Interface Read Back the Input Power to the PDs and the Bias Voltages Through GUI Read Back the Firmware Version Through GUI Low Profile: 90.7 x 85.6 x 16.5 mm Detector Input Power: -25 dBm Min., -10 dBm Max.
