Free Space Acousto-optic Modulator

The high-power, high-speed fiber acousto-optic modulator (AOM) is one of the core components of all-fiber laser. It has the advantages of ultra-high extinction ratio, low insertion loss and fast rise time, and can select and modulate pulse lasers.

Product introduction

Acousto-optic modulators,which utilize the acousto-optic effect toachieve optical modulation,employ acoustic waves generated by amodulation signal within the modulator to alter the device's refractiveindex.This,in turn,modifies the phase of light passing through thedevice,achieving the modulation objective.Dayoptics' offers acousto-optic modulators made fromTeO2material,characterized by high laser damage thresholds, high powerhandling,and high extinction ratios.Our standard product line includeskey operating wavelengths such as 1030 nm and 1064 nm,withmodulation frequencies available in 80,100,120,150and 200 MHz.Additionally,our free-space series features various aperture sizes and canbecustomized to meetspecific customerrequirements.
