AOM Fiber-coupled Acousto-optic Modulators

Wavelength 450-200 nm; Pigtail Type SM, PM; Rise / Fall Time 6-100 ns; Operating Frequency 40-300 MHz; 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 Series Product Code Wavelength Pigtail Type Rise / Fall Time Operating Frequency Downloads Fiber-Q 1060 nm 150 MHz Non-Hermetic Fiber-Coupled AOM S-M150-0.4C2G-3-F2S 1060 nm SM 30 ns 150 MHz Datasheet Datasheet Datasheet Driver Fiber-Q 1060 nm 200 MHz Non-Hermetic Fiber-Coupled AOM S-M200-0.1C2G-3-F2P 1060 nm SM 10 ns 200 MHz Datasheet  Driver   Driver  Driver Fiber-Q 450 nm 200 MHz S-M200-0.4C2A-3-F2P, S-M200-0.4C2A-3-F2S 450 nm PM, SM 25 ns 200 MHz Datasheet  Driver   Driver  Driver  Fiber-Q 532 nm 200 MHz S-M200-0.4C2C-3-F2P, S-M200-0.4C2C-3-F2S 532 nm PM, SM 25 ns 200 MHz Datasheet  Driver  Driver     Fiber-Q 633 nm 200 MHz Fiber Coupled AOM S-M200-0.4C2E-3-F2P, S-M200-0.4C2E-3-F2S 633 nm PM, SM 25 ns 200 MHz Datasheet  Driver   Driver    Fiber-Q PM 1550 nm, 40 MHz (AMTIR) T-M040-0.5C8J-3-F2P 1550 nm PM 100 ns 40 MHz Datasheet  Driver  Driver  Driver  Fiber-Q 1550 nm 40 MHz (AMTIR) T-M040-0.5C8J-3-F2S 1550 nm SM 100 ns 40 MHz Datasheet Datasheet Datasheet Driver  Fiber-Q PM 2000 nm 80 MHz Hermetic Fiber Coupled AOM T-M080-0.3C2Z-3-F2P 2000 nm PM 100 ns 80 MHz Datasheet  Driver      Fiber-Q 2000 nm 80 MHz Hermetic Fiber Coupled AOM T-M080-0.3C2Z-3-F2S 2000 nm SM 100 ns 80 MHz Datasheet  Driver     Fiber-Q PM 1550nm 80MHz Hermetic Fiber-Coupled AOM T-M080-0.4C2J-3-F2P 1550 nm PM 35 ns 80 MHz Datasheet  Driver     Fiber-Q 1550 nm 80 MHz Hermetic Fiber Coupled AOM T-M080-0.4C2J-3-F2S 1550 nm SM 35 ns 80 MHz Datasheet  Driver     PM Fiber-Q Polarization Maintaining 1550 nm Hermetic Fiber Coupled Acousto-Optic Modulator, 80 MHz (Low Power Consumption) T-M080-0.5C8J-3-F2P 1550 nm PM 100 ns 80 MHz Datasheet  Driver      Fiber-Q 1550 nm Hermetic Fiber Coupled Acousto-Optic Modulator, 80 MHz (Low Power Consumption) T-M080-0.5C8J-3-F2S 1550 nm PM 100 ns 80 MHz Datasheet  Driver      Fiber-Q PM 1550 nm 110 MHz Hermetic Fiber Coupled AOM T-M110-0.2C2J-3-F2P 1550 nm PM 25 ns 110 MHz Datasheet Driver       Fiber-Q 1550 nm 110 MHz Hermetic Fiber Coupled AOM T-M110-0.2C2J-3-F2S 1550 nm SM 25 ns 110 MHz Datasheet  Driver      Fiber-Q PM 1060 nm 150 MHz Hermetic Fiber Coupled AOM T-M150-0.4C2G-3-F2P 1060 nm PM 30 ns 150 MHz Datasheet  Driver     Fiber-Q 1060 nm 150 MHz Hermetic Fiber-Coupled AOM T-M150-0.4C2G-3-F2S 1060 nm SM 30 ns 150 MHz Datasheet  Driver     Fiber-Q, 780 nm, 150 MHz Fiber Coupled AOM T-M150-0.5C2W-3-F2P, T-M150-0.5C2W-3-F2S 780 nm PM, SM 50 ns 150 MHz Datasheet  Driver     Fiber-Q PM 1060 nm 200 MHz Hermetic Fiber Coupled AOM T-M200-0.1C2G-3-F2P 1030 - 1090 nm PM 10 ns 200 MHz Datasheet  Driver Driver     Fiber-Q 1060 nm 200 MHz Fiber Coupled AOM T-M200-0.1C2G-3-F2S 1060 nm SM 10 ns 200 MHz Datasheet  Driver  Driver  Driver  Fiber-Q PM 1550 nm 200 MHz Hermetic Fiber-Coupled AOM T-M200-0.1C2J-3-F2P 1550 nm PM 10 ns 200 MHz Datasheet  Driver Driver     Fiber-Q 1550 nm 200 MHz Hermetic Fiber-Coupled AOM T-M200-0.1C2J-3-F2S 1550 nm SM 10 ns 200 MHz Datasheet  Driver Driver     Fiber-Q 2000 nm (2µm) 250 MHz Fiber Coupled AOM T-M250-0.3C16Z-3-F2P 2000 nm PM 20 ns 250 MHz Datasheet  Driver      Fiber-Q 1060 nm 300 MHz Hermetic Fiber Coupled AOM T-M300-0.1C2G-3-F2P, T-M300-0.1C2G-3-F2S 1060 nm PM, SM 6 ns 300 MHz Datasheet  Driver      Fiber-Q 1550 nm Fiber Coupled Acousto-Optic Modulator T-M300-0.1C16J-3-F2P 1550 nm PM 6 ns 300 MHz Datasheet Driver      

Wavelength 1030-2100 nm; Active Aperture 1-8 mm; Operating Frequency 24-80 MHz; Optical Material Crystalline Quartz, Fused Silica; Type Water Cooled, Conduction CooledAn acousto-optic Q-switch (AOQS) works within a laser cavity to generate high intensity, pulsed light by actively controlling the Q-factor (loss) of the cavity. The acousto-optic Q-switches available from Gooch & Housego (G&H) are rugged, reliable and long-lasting. The product offering includes low insertion loss and highly efficient acousto-optic Q-switches capable of handling very high peak power. Particular attention is used to match the cavity length, repetition rate, wavelength, beam diameter, polarization state and output power of a laser to the best acousto-optic Q-switch solution.G&H offers off-the-shelf solutions for polarized or unpolarized lasers at near infrared wavelengths. G&H can accommodate large lamp pumped multimode laser beam diameters (up to 8 mm) as well as small compact diode pumped beam diameters (< 1 mm) with both water and conduction cooling.

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.
