We present detailed calculations of the temporal and spatial evolution of beam fanning in
photorefractive crystals that is initiated by scattering from noise. We show that fanning starts …

A model to describe the fanning effect based on the beam-coupling mechanism in
photorefractive crystals is presented. The intensity distribution of the fanning beam in a 45° …

A model to describe fanning effects in photorefractive crystals is presented. The intensity
distribution of the fanning beam for one incident beam and two incident beams in 45°‐cut …

Using a perturbational-analysis and Fourier-transform techniques, we solve the Kukhtarev
equations to analyze the steady-state and the transient beam fanning in a photorefractive …

Self-defocusing of a Gaussian light beam in a bulk photorefractive BaTiGl crystal is
demonstrated. This is a low light intensity process which results from the coupling and power …

We investigate the dynamics of multiple two-wave mixing in photorefractive materials. This is
the first time to our knowledge that a study of the dynamics of many pairs of two-wave mixing …

Propagation of the light beam in a thin photorefractive crystal with the diffusion-type
mechanism of nonlinearity has been studied both experimentally and theoretically. Total …

We demonstrate that two-wave mixing of partially coherent light beams inside a medium with
an inertial nonlinear response allows one to increase the coherence substantially. An …

We demonstrate a new type of scattering process induced by two mutually incoherent
beams in photorefractive crystals. The input beams may be of different colors. Dark and …
