We investigate contradirectional two-wave mixing with partially coherent waves in
photorefractive crystals in the nondepleted pump regime. Equations governing the …

Combined effects of cross and parallel coupling have been investigated in the case of
contradirectional two-wave mixing in an absorbing photorefractive crystal. Nonlinear …

The effect of multiple internal reflections on the stationary energy transfer in degenerate two-
wave mixing, in a reflection geometry, with photorefractive crystals is studied. Numerical …

We study here the four-wave mixing in photorefractive crystals with light beams of partial
temporal coherence. We consider the evolution of the mutual coherence of the beams due to …

A novel method for the exact solution of four-wave mixing in photorefractive media is
presented. This method allows us to treat exactly the effects of nonequal angles of …

We consider symmetries of two-wave mixing equations in photorefractive crystals, using
group theoretical methods. Symmetry groups for both the equations and conserved …

We investigate the effect of beam temporal coherence on four-wave mixing via transmission
gratings in photorefractive media. We take into account the propagation of mutual coherence …

We extend the standard model of four-wave mixing in photorefractive crystals to the case
where the Bragg-condition is broken by a slight departure from degeneracy. Our analytical …

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 …
