Abstract

The properties of anisotropic diffraction of light by crossed-beam volume holographic grating in photorefractive crystals are discussed. The amplitude profiles and the diffraction efficiency of the transmitted and diffracted beams are calculated. The profile of the diffracted beam is influenced strongly by the deviation from the Bragg case. It is demonstrated that the anisotropic diffraction of crossed-beam volume grating in photorefractive crystals has excellent angular and wavelength sensitivity.
