EM4''s product family of fiber coupled Acousto Optic Modulators and Isolators are rugged hermetic sealed modules that have been designed and built using technologies and processes developed for
An acousto-optic modulator (AOM), also called a Bragg cell or an acousto-optic deflector (AOD), uses the acousto-optic effect to diffract and shift the frequency of light using sound waves (usually at radio
EM4 Inc. in Bedford, Mass., is offering a series of ruggedized small-form-factor fiber coupled acousto optic modulators and high-power handling fiber coupled isolators for defense,
What Are Acousto-optic Modulators? An acousto-optic modulator (AOM) is a device which can be used for controlling the transmitted power of a laser beam with an electrical drive signal.
Fiber Coupled Acousto-Optic Switch/Modulator/Shifter – 0.5dB Low Loss, up to 30W High Power 80Mhz, 1x2, 20MHz, repetition rate, 15ns rise/fall, 400-2000 nm, bidirectional
If you require either fast repetition rates or large aperture sizes, our acousto-optic modulators are optimized for low scatter and high laser damage threshold, for reliable operation in a wide range of
Acousto-optic modulators (AOM) are generally used outside the laser cavity to change the intensity of the incoming laser (amplitude-modulated AM). This can be simple ON/OFF modulation for quick
These devices utilize the acousto-optic effect to diffract a portion of incident light at a deflection angle. They are useful for applications that require high speed modulation of light in an optical system.
Turn on the AOM and position it at the beam focus, less a small distance to account for the increased optical path length inside the modulator crystal. This increment is of the order of millimeters and can
It is pigtailed with polarization maintaining fiber on the input and output as required and contains internal circuitry for 50Ω RF matching. With rise/fall times of 40ns it can be used in fast pulse picking and
