ACOUSTO-OPTICS

Acousto-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. Our acousto-optic modulators are optimized for low scatter and high laser damage threshold. Rise time, modulation rate, beam diameter, and power handling needs of the application need to be understood in order to identify the best acousto-optic modulator and RF driver solution.

An 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. Our acousto-optic Q-switches are rugged, reliable, and long-lasting, backed by millions of hours of service in the field.

Acousto-optic tunable filters (AOTF) are used to rapidly and dynamically select a specific wavelength from a broadband or multi-line laser source. As the applied RF frequency is varied, the transmitted wavelength changes, “tuning” the wavelength of the beam or image in tens of microseconds or less.

Acousto-optic beam deflectors (AOBD) provide precise spatial control of an optical beam, whether performing 1D or 2D scanning or executing beam deflection through a fixed angle.

Transmission through an acousto-optic (AO) device causes the input light to experience a frequency shift equal to the RF drive frequency. Our acousto-optic frequency shifters (AOFS) are optimized for the needs of applications like interferometry, with the ability to achieve high extinction ratio between modes.

Fiber-coupled acousto-optic modulators (FCAOM) offer a compact and robust solution for fiber laser modulation and frequency shifting, allowing direct control of the timing, intensity, and temporal shape of the laser output. Our Fiber-Q™ modulators offer high extinction ratio, low insertion loss, and excellent stability in both single-mode and polarization maintaining formats at modulation frequencies up to 30 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.

Wideband RF amplifiers available in OEM and bentchtop case versions. The main features are: linearity, high dynamic range and low noise.
