Paper Abstract

The high-modulated phase gratings induced in photorefractive crystals are anharmonic. For small angles between incident beams (thin grating regime), an additional mixing can appear between the diffraction orders produced by harmonics of the anharmonic grating. This mixing yields significant changes in the self-diffraction spectra. Our theoretical and experimental results explain the effect of the grating anharmonicity on the self-diffraction on thin photorefractive gratings.
