摘要
从波动性和粒子性两个方面对声光互作用进行了讨论,由耦合波方程得到Bragg衍射的衍射效率,依据光子和声子相互作用的能量守恒和动量守恒得到衍射光相对于入射光偏转角的关系式,衍射光和入射光之间频率的关系式,以及反常Bragg衍射入射光波长受超声波频率控制的关系式,基于声光互作用的特性展开了声光器件在激光技术领域中的应用研究,并进行了归纳总结。
Acousto - optic interaction is discussed based on the wave and particle character of photon and phonon. First, the diffraction efficiency of Bragg diffraction light deduced from coupling- wave function is introduced. Second, the relation between the deflection angle and frequency of incidence light and of diffraction light is presented form the point of momentum conservation and energy conservation. At last, the use of acousto -optic detector is summarized in the field of laser technology.
