This article introduces an acousto-optic modulator, with six channels, that achieves parallel and independentmodulation of six laser beams by preparing electrode arrays on the transducer, designing independent impedancematching circuits and electrical input interfaces, and integrating six acousto-optic interaction units.The acousto-optic modulator has an optical wavelength of 355 nm, a working frequency of 220 MHz, a diffraction efficiencyof over 75% for each channel, and a global cross-talk below 0.5%.
