Bragg Diffraction of Light from Ultrasound in Cubic Centrosymmetric Crystals in an External Electric Field

摘要

Special features of noncollinear Bragg diffraction of light from ultrasound in centrosymmetric cubic crystals placed in an external electric field are considered. Particular cases of acousto-electro-optical interaction on (quasi-)longitudinal and (quasi-)transverse acoustic waves propagating in the (001) and (110) planes are analyzed. The dependence of diffracted light energy characteristics on photoelastic and electro-optical param-eters of a cubic centrosymmetric crystal, as well as external field strength and orientation, is determined.
