摘要

我们提出了一种用长程位错变形场描述HRLS的现象学方法。为了描述光与位错的非线性相互作用，我们使用非线性光弹性张量来研究声诱导光学二次谐波的产生。考虑了一种无倒位中心的立方晶体(如GaAs，其特征为对称点群T/sub / d/)具有线性边缘位错。

Hyper-Rayleigh light scattering by dislocation deformation

We present a phenomenological description of HRLS by long-range dislocation deformation fields. For the description of nonlinear interaction of light with dislocations we use a nonlinear photoelastic tensor for investigation of acoustically-induced optical second harmonic generation. A cubic crystal without inversion center (for example GaAs, which is characterized by the symmetry point group T/sub d/) with linear edge dislocation is considered.
