1550nm Acousto Optic Modulator Module

1550nm Acousto Optic Modulator Module (AOM) is a kind of extenal optical modulator with RF driver intergrated inside, it’s built with Tellurium dioxide crystal, which can modulate the light optical power, Phase, intensity or phase shift, it based on Acousto-optic effect to change the refractive index of crystal through mechanical strain caused by the oscillation of sound waves, the operating wavelength from visible light to infrared light, it’s widely used in Ultrafast Laser, Doppler Coherence, Q-switched Laser and LIDAR System, it features fast response time, low insertion loss, high extinction ratio and high reliability, the parameter can be customized upon request.
