摘　　要：通过对三方、四方、六方和立方晶系的纵向电光效应和三维反常声光效应的研究,选定了立方晶系的GaP晶体作为三维声电光器件的最佳晶体,并确定了其最佳工作模式为:电场和光传播方向沿[111]方向;3个超声纯切变波的传播和偏振方向都在与[111]垂直的平面内,互成60°角。研究结果为三维声电光器件的设计与制作打下了良好基础。In this paper the longitudinal electrooptic effect and the threedimensional anisotropic acoustooptic effect in trigonal system,square system,hexagonal system and cubic system are researched.An optimum crystal GaPand its mode of operation are determinated.The electric field is applied in the direction,and the laser propagates in the direction also.Three transverse ultrasonic waves propagate and vibrate in the plane vertical to the direction with 60° each other.The research results will lay the foundations for the design and manufacture of the threedimensional acoustoelectrooptic device.Key wrods:threedimensional acoustoelectrooptic interaction;anisotropic acoustooptic effect;longitudinal electrooptic effect
