摘要
介绍了一种6信道声光调制器.通过在换能器上制备电极阵列,设计独立的阻抗匹配电路和电输入端口,将6个声光互作用单元集成在一起,实现了对6束激光的并行、独立调制.经测试,该6信道声光调制器工作波长为355 nm,工作频率为220 MHz,单信道衍射效率>75%,全局串扰<0.5%.
Abstract
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% .
