Abstract

We have considered some special cases the interaction of optical radiation and photorefractive crystals. We gave special attention to the impact of the characteristics of optical radiation, the intensity, frequency and polarization of the wavefront onto the features of the large-scale and small-scale optical defects forming due to the photorefractive effect in crystals. We registered forming of the small-scale optical defects via observing of the photoinduced light scattering in photorefractive lithium niobate crystals. And we registered forming of the large-scale optical defects in lithium niobate crystals by the polarizers system. Lithium niobate crystals have significant electro-optical and photorefractive properties. They are convenient model for studying how the light waves propagate through the photorefractive crystals. The article discusses the results of the experiments.
