Abstract

Rigorous coupled-wave diffraction theory is used to analyze two and multi-wave mixing in diffusion-controlled photorefractive barium titanate which is modeled by the Kukhtarev equations. The transmitted and reflected optical fields, the dielectric modulation, the electrostatic electric field, and the electron density are studied for the cases when the interfering, incident optical fields have equal and unequal amplitudes, for different values of the linear refractive index mismatch and for different values of photorefractive crystal length. Our computations are extended to include longitudinal variations of the electrostatic field. Temporal instabilities and higher order generation are examined.
