Relation between Photoelasticity, Electrostriction, and First-Order Raman Effect in Crystals of the Diamond Structure

Abstract

A lattice theory of the elasto-optic and electrostriction constants of crystals of the diamond structure is presented. The results of the theory relate these constants to the derivatives of the electronic polarizability which determine the intensity of the first-order Raman scattering of light by such crystals. Experimental values of the elasto-optic constants are used to estimate the electronic polarizability derivatives for diamond, germanium, and silicon.
