- Abstract
An analytical theory of the polarization-degenerate interaction of light waves in cubic photorefractive crystals of the 23 and &4macr;3m space symmetry groups is proposed. The theory, based on a systematic use of the spatial symmetry properties and the σ-matrix apparatus, provides for a unified description of the polarization and orientation properties of the wave interactions, including the AC and DC methods for enhancement of the nonlinear response and the influence of optical activity, elastooptical effect, and spatial inhomogeneity. The application of the theory to the description of the properties of photorefractive crystals Bi[sub 12]TiO[sub 20] and Bi[sub 12]SiO[sub 20] shows a good agreement with experimental data.
