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 …

A general two-dimensional model to describe beam fanning, which takes into consideration
the finite width of the input beam and the interaction between different directions of the …

A nonlinear optical phenomenon, namely, the surface waves in photorefractive crystals with
a diffusion nonlinearity (of the gradient type), is suggested and analyzed. These waves can …

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° …

All the possible types of surface light wave that can exist on the boundary of a
photorefractive uniaxial crystal with a diffusion-drift nonlinearity mechanism are identified. It …

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 …

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 …

A laser beam propagating in a photorefractive crystal generates a refractive-index profile
that deflects the beam to one side. This nonlinear deflection can be balanced by total …

Interactions between optical beams incident upon and higher‐order self‐diffracted beam
generated within an absorptive and optically active photorefractive crystal of 23 symmetry …
