Abstract

The theory for two-wave mixing in a photorefractive material with an external electric field and a moving grating is developed. Large gain enhancements are predicted for grating periods of 10–100 μm and compared with recent observations in Bi₁₂SiO₂₀. Predictions are made for enhancements in GaAs, which has recently been found to be photorefractive in the near infrared.
