声光晶体声光晶体acoustoopticalcrystal具有声光效应的晶体材料。晶体在外力作用下会引起其折射率的变化，从而导致其光学性质的改变，这一现象称为弹光效应。当超声波（机械波）通过介质材料时，要在介质材料中产生弹性力，从而通过弹光效应使介质材料的折射率发生变化，这即为声光效应。声光晶体的最大特点是光学和声学的各向异性。由于各向异性使声光晶体在声光效应中具有反常布拉格衍射效应，从而开发出宽带、快速的反常布拉格衍射声光调制器和声光滤波器。声光晶体的各向异性，又使其可能在某些方向获得很小的声速和高的品质因子。此外，晶格的长程有序排列，又使声光晶体一般具有较小的声损耗，从而可以增大声光器件的带宽。常用的声光晶体有：①立方晶类声光晶体。主要有石榴石型晶体、BSO和BGO晶体。一般有比较成熟的生长工艺，易于获得较大尺寸的单晶。其弹光系数小，品质因子较低，但其声损耗小，可制作宽带的声光器件。②光学单轴声光晶体。一种应用最广的声光晶体。主要有二氧化碲、钼酸铅、氯化亚汞等。较容易生长，不易获得大尺寸，弹光系数较大，折射率和品质因子高。③光学双轴声光晶体。主要是正交晶系的a-HIO3，此外还有研究发展中的溴化铅晶体。其对称性较低，有较强的各向异性，晶体生长较困难，不同种类晶体的品质因子差别很大，从而提供了多种器件设计方案。④半导体声光晶体。用于红外波段的主要声光晶体。有三分晶系的TAS和Ag3AsS3，立方晶系的碲和锗单晶。其折射率大，弹光系数大，品质因子高，但其声损耗较大，带宽较小。
