Hyper-Rayleigh light scattering by dislocation deformation

Abstract

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.
