Abstract

Theory of collinear acousto-optic interaction in anisotropic media has been considered. On the base of the statement that anisotropic diffraction of light by ultrasound originates from the acoustically induced changes of optical indicatrix in an anisotropic medium, the qualitative and quantitative analysis of the collinear AO interaction has been carried out. The collinear diffraction has been examined in the medium subdivided into a number of thin layers. In each of these layers, the axes of the indicatrix are rotated relatively to the neighboring ones. It has been shown that propagation of light through such system may be considered as propagation through a number of birefringent plates, rotated relatively to each other. The analytical expressions for the intensities of the incident and diffracted light have been derived. It has been shown that the diffraction efficiency depends on the angle of rotation of the axes and on birefringence of the crystal. In the case of a big number of the layers, the calculations have been carried out with the help of Jones calculus and the efficiencies of the collinear diffraction in the most commonly used acousto-optic materials such as paratellurite, α-quartz and tellurium crystals, have been calculated.
