When three incident mutually coherent beams interact by degenerate four wave mixing in a
photorefractive medium, four gratings are induced: 1 (1) a transmission grating,(2) a …

We present measurements of the two-wave mixing gain as a function of frequency detuning
in photorefractive crystals. In many cases, this function is asymmetric, indicating that the …

We have studied the four wave mixing with partially coherent waves in photorefractive
crystals with the transmission grating approximation both theoretically and numerically. The …

Two-wave mixing in photorefractive crystals in various configurations has been investigated
extensively. Most of the previous works in this area are on wave mixing with mutually …

We consider phase conjugation via degenerate four-wave mixing in photorefractive crystals
when more than one grating mechanism is operative. A method for exact solution of the …

In this paper we propose that competition between multiple gratings for charge carriers in
degenerate four-wave mixing (DFWM) is responsible for the following experimentally …

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 present an analysis of multiple beam coupling and grating formation within a
photorefractive crystal positioned adjacent to a phase conjugate mirror. We include the …

The structure and dynamics of the four-wave mixing transmission grating in a photorefractive
crystal were investigated. The steady-state grating s amplitude distribution looks like a …
