Abstract: The problem of the forward four-wave mixing on phase holographic gratings in a cubic photorefractive absorbing crystal of symmetry class 23 is considered. The dependence of the reflection coefficient on the thickness of a crystalline sample has been studied. Conditions under which the reflection coefficient value optimized in terms of the azimuth of the linear polarization of light waves reaches its highest values have been established. The effect of phase shifts between the holographic gratings and corresponding interference patterns on the intensity of the phase-conjugated wave is discussed.

Keywords: photorefractive crystal, four-wave mixing, holographic grating, reflection coefficient, diffraction efficiency.
