摘要：

The appearance of the photorefractive effect on all optical polling (OP) of a bulk glass is investigated. During OP, a refractive-index grating accumulates in the glass and radiation effectively diffracts through it. The theory of the self-diffraction of light has been developed and the resultant expression for the amplitude of the diffracted light has been deduced, considering the geometry of formation of the refractive-index grating in glass upon interaction of the intersecting Gaussian beams. The results of the experimental investigation of the diffraction of light on the photorefractive gratings induced in some oxide glasses have been presented. The experimental results obtained are in agreement with the theory, based on a model of formation of a spatially periodic electrostatic field in glass via the coherent photogalvanic effect. The phenomenon of light diffraction can be used to investigate the physical properties of all OP in different glass media and to search for new, effective photorefractive materials.
