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 …

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 propose and analyze a new type of phase conjugation between counterpropagating
beams in photorefractive materials based on diffraction from transmission gratings only. This …

In this paper we show that it is possible to make a heterodyne interferometer with a single
photorefractive BGO crystal using the technique of moving gratings. The main problems of …

The coupled wave equations for four-wave mixing (FWM) in a cubic, non-optically-active
photorefractive crystal are solved for the case of orthogonally polarized pumping beams. For …

We show that the standard model of four-wave mixing in a photorefractive crystal predicts
the appearance of deterministic chaos. In this model there is a single (transmission) grating …

It is shown that it is possible to increase dramatically the efficiency of stationary four-wave
mixing in cubic photorefractive crystals of the sillenite family. In order to do this one has to …

In this letter we demonstrate and explain the lack of spatial information crosstalk between
beams in various oscillators by photorefractive CPR) wave mixing (WM). 1, 2 This study is …

A two-dimensional model for the self-pumped phase conjugation in photorefractive crystals
is presented. Numerical simulations of the beam path for beam fanning and the self-pumped …

A numerical simulation is reported of a one-pass system for suppression of dynamic
distortions, which is based on four-wave mixing of optical fields in photorefractive crystals. A …
