The acousto-optic multi-channel modulator integrates a set of transducer arrays with a single acousto-optic crystal to achieve independent modulation or deflection of multiple laser beams.
Our acousto-optic multi-channel modulator has the advantages of large aperture, high RF power resistance, and fast modulation speed. It supports up to 48 channels for simultaneous modulation and up to 8 channels for beam deflection. Through proprietary optical and electrical designs, it minimizes crosstalk effects and covers wavelengths from ultraviolet to infrared bands. It has the characteristics of high carrier frequency, large modulation bandwidth range, short rise time, high damage threshold, high diffraction efficiency, and multi-channel independent control and simultaneous output.
We achieve high laser damage thresholds by using low-scattering materials and meeting stringent quality standards. We refine our own tellurium oxide and source high-quality fused and crystalline quartz to ensure low insertion loss and excellent optical power handling.
