An analytical model has been developed to describe both drift and diffusion mechanisms of nonlinear response (local and nonlocal components of nonlinearity) of photorefractive crystals (PRCs) on a microscopic level. Some types of stable self-consistent distributions of light intensity — bright and dark photorefractive spatial solitons — have been considered. Paths of their propagation (self-bending) have been calculated and a possibility of formation of a new type of soliton-like distributions — spatial shock waves — has been shown. Analysis of plane wave modulation instability has been performed and specific spatial scales of light distribution, resulting from self-action processes (fanning), have been calculated. All the analytical results have been confirmed using computer simulation.
