Abstract

Some results on theoretical and experimental investigation of acousto-optical devices based on paratellurite single-crystals are presented. The operation principle of the devices is based on optical beam diffraction by acoustic diffractional gratings in TeO₂ during a non-collinear geometry of interaction as well as in near-collinear regime of scattering. The devices use light diffraction on shear acoustic waves propagating along (110) axis of paratellurite and close to this direction. Depending on the directions of acoustic and optical beam propagation in acousto-optical cells, three regimes of acousto-optical interaction were realized with different selectivity of Bragg anisotropic scattering. Some peculiarities of device operation are analyzed in the paper and possible applications of the acousto-optical devices for optical information processing are discussed.
