Abstract

The phenomenon of the light diffraction by the elastic waves in crystals has been considered on the basis of the coupled waves method in somewhat different form than it was earlier considered by other researchers. The difference is determined by the address to two pairs of the orthogonal coordinate systems whose main axes are oriented in the directions of the phase and the energy movements of two optic waves interacting via the `sound'. As a result the coupled mode equations are obtained in most compact, not complete previously known form for the crystals. They admit the traditional solutions in the form of the quasiplanar waves and assume more wide class of solutions for the restricted interaction regions. The comparative analyze of two different diffraction regimes--on transmission and on reflection--is made. The represented consideration allows to formulate in correct form the parameters, determining the light diffraction efficiency by elastic waves in crystals.
