Combined acousto-optic device from optically birefringent crystal

摘要

Combined acousto-optic device formed by a cut from optically birefringent single crystal whose one face, parallel to the direction of the principal crystallographic axis, is provided with at least one piezoelectric source of acoustic waves. At that, the normal to the entrance face of the ordinary and extraordinary light beam is inclined from the direction of principal crystallographic axis by an angle rho defined by formula rho =arc tg(ne/no)+/-20 DEG , in which the symbols ne and no denote the refractive indices of the extraordinary and ordinary light beams in the single crystal.
