Acoustooptic Bragg diffraction in anisotropic optically active media.
Coupled-mode equations are established for the acoustooptic interaction of plane waves in anisotropic, optically active crystals. A method of solution is proposed which allows for spatial variation of the optical polarization modes. An analysis of the slow shear wave TeO(2) Bragg cell is given with numerical results for diffraction efficiency and polarization of the optical beams as a function of distance travelled in the cell. Large departures of the optical polarization from pure circular polarization are evident as the acoustic power is increased.
