Аннотация: Peculiarities of light diffraction on ultrasonic waves in glasses and birefringent crystals are examined thoeretically and experimentally. Isotropic dense flint glass material DF-7 and optically anisotropic crystal of tellurium dioxide were chosen for the investigation. The diffraction was observed in intermediate and Bragg regimes of aocusto-optical interaction. From five to seven diffractional maxima in a diffractional pattern were considered in the theoretical research. Intensitites of zero, forst, second, and third diffractional orders were measured during the experiments. Special attention was devoted to analysis of the diffraction in the second diffractional order. Intensities in the second maximum up to 60% in the glass and up to 80% in the crystal were obtained. Applications of the investigated phenomena in acousto-optical devices for scanning and frequency shifting of light are discussed in the paper as well.
