General Description
Acousto-Optic Multi-Channel Modulators (AOMM) are advanced devices designed to modulate or deflect multiple optical beams simultaneously. By integrating transducer arrays into a single acousto-optic crystal, AOMMs significantly increase the number of modulated beams, reduce scanning rates, and lower modulation bandwidth, improving overall linearity and efficiency.
Compared to single-channel AOMs, AOMMs provide independent control of multiple beams or collimated light lines, making them ideal for demanding applications such as laser color printers, multi-channel acousto-optic spectrometers, optical digital computers, and video infrared image processing systems.
POC’s AOMMs are constructed using low-scatter fused quartz, crystalline quartz, and Tellurium Dioxide to ensure low insertion loss, high diffraction efficiency, and robustness under high-power conditions. These modulators support up to 10 channels and operate at frequencies up to 200 MHz, minimizing acoustic and electrical crosstalk while delivering precise performance.
