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
