Fiber-coupled acousto-optic modulators (FCAOM) offer a robust solution for amplitude modulation of fiber lasers, allowing direct control of the timing, intensity, and temporal shape of the laser output. 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. The fast switch rate Fiber-Q® devices enable efficient, high speed optical pulse picking at infrared wavelengths for all-fiber laser systems. Most devices are also offered in 3-port configurations.

Applications: Industrial Lasers; Sensing; Scientific Research; Telecommunication; Quantum Technology; Optical Heterodyne Interferometry; Microscopy; Flow Cytometry

SF8XXX Laser Diode Drivers and TEC Temperature Controllers

Output Current LD 0.25-1.5 A; Output Current TEC ±4 A; Chassis Mount; Compatible with Butterfly Type 1 & Type 2 Lasers; Current Stability <0.1% Maiman Electronics’ SF8XXX series of laser diode drivers and TEC temperature controllers are suitable for driving fiber coupled laser diodes in a butterfly package with 10 or 14 pins. SF8XXX series drivers are available with pinouts for Type 1 (Pump) or Type 2 (Telecom, SF8XXX-T) butterfly laser diodes. The SF8XXX drivers include highly stable (±0.01 A) current sources for the laser diode and a thermoelectric Peltier cooler (TEC). The integrated temperature controller keeps the temperature on the Peltier element with high precision within ±0,01 °C. The laser diode driver circuit of the SF8XXX series is a non-isolated low drop-out (LDO) regulator with constant current output, producing current with high stability and low ripple. The TEC driver circuit is a non-isolated DC/DC converter, producing low current ripple. Additional features of the SF8XXX series include an adjustable TEC output current limit and an integrated self-adjusting PID controller, providing optimal temperature regulation. All SF8XXX can be controlled by analog signal or digital signals and switches on the board. The SF8xxx series drivers are housed in a 61 × 101.6 mm enclosure with aluminium base plate to aid thermal dissipation from the laser diode. SF8xxx series drivers can be mounted on any surface that is thermally conductive enough to dissipate the laser diode’s power loss. The laser diode mount is located on the board – either with landing pads for soldering a butterfly laser diode directly into driver board or with an integrated mounting Azimuth socket for butterfly packaged devices (-ZIF types). Key Features: All-in-One Current Source, Temperature Controller and Mount (ZIF-10/ZIF 14 types with Azimuth ZIF Socket) for Butterfly Laser Diodes Compatible with Type 1 Butterfly 10-pin, Type 1 / Type 2 Butterfly 14-pin Laser Diode (Depending on Model) Low Laser Diode Current Ripple: ≤10 µA Laser Diode Current Stability <0.1% Integrated PID Controller, Does Not Require Setup Soft-Start Current Ramp, Current Limit, Temperature Limit for Laser Diode Protection Free Software NTC Thermistor Input Analog Control Signal / RS-232 Possibility to Calibrate Current Within 5% Applications: Supplying Laser Diodes in Butterfly Package; Laser Pumping; Laser Spectroscopy; Laboratory Test Set-ups

Acousto-Optic Modulators

Wavelength 5.5 µm-1090 nm; Rise / Fall Time 10-160 ns/mm; Active Aperture 0.1-9.6 mm; Operating Frequency 40-200 MHz; Optical Material Crystalline Quartz, Germanium, Tellurium Dioxide; Type IR, Mid-IR, Visible, UVAcousto-optic modulators (AOM) allow the intensity of light to be controlled and modulated at rates that far exceed mechanical shutters, even up to 70 MHz. 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
