摘要： An acousto-optic modulator includes a (100), (010) or (001) single crystal silicon acousto-optic interaction medium, and at least one transducer for emitting an acoustic wave attached to the single crystal. The transducer has a first electrode layer disposed on one side and a second electrode layer disposed on its other side. The transducer is aligned to the single crystal so that the direction of acoustic propagation in the silicon crystal is substantially along the (100), (010) or (001) direction. A q-switched laser includes a modulator according to the invention.

摘要： An acousto-optic (AO) frequency shifter includes an anisotropic crystal having an optical axis and an input face, and an acoustic transducer having electrodes affixed to the face for receiving an electrical signal and projecting an acoustic wave into the crystal. The anisotropic crystal is cut relative to the face so that the transducer is at an acoustic angle (θa) corresponding to a predetermined angle of incidence (θi) of an optical beam to be directed relative to the optic axis of the anisotropic crystal to substantially satisfy the parallel tangents phase matching condition.
摘要翻译： 声光（AO）移频器包括具有光轴和输入面的各向异性晶体，以及声传感器，其具有固定在面上的电极，用于接收电信号并将声波投射到晶体中。 各向异性晶体相对于面切割，使得换能器处于与相对于各向异性晶体的光轴指向的光束的预定入射角（θ）相对应的声角（θa），以基本满足 并联切线相位匹配条件。
