Abstract
The nonlinear problem of speckle-beam propagation in a photorefractive crystal with a strong diffusion-grating response has been solved. The approximate self-sustaining solution has been found that conserves th e Gaussian shape of an angular spectrum of the beam but gradually tilt s its propagation direction. The rate of angular tilting is proportion al to the square of the beam's angular divergence and depends on the c rystal-axis orientation.
