Abstract

The formation of photorefractive grating at the symmetric three-wave forward interaction in a cubic optically activity crystal with applied ac electric field is considered for small contrast of interference light pattern. The self-consistent equations describing spatial-temporal dependency of modulation index and amplitude of space charge field is obtained. For high frequency of external field it is shown the interaction reaches of steady state only at the linear polarization of pump light wave. The dependencies of modulation index on interaction length are analyzed for interaction in Bi₁₂TiO₂₀ and Bi₁₂SiO₂₀ crystals with diagonal electro-optic configuration.
