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