We present a theory of the frequency-detuning properties of various oscillators formed by
four-wave mixing in photorefractive crystals. It is shown that the detuning originates from the …

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 …

We report on an experimental study of the self-frequency detuning in wave mixing oscillators
with the photorefractive barium titanate crystal. We show its dependence on a dc electric …

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 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 …

The theory of grating oscillations in photorefractive materials is developed in the linear and
nonlinear approximations for the drift mechanism of holographic recording. The resonance …

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 …

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 a previous Letter [1] we described a new type of optical interferometry based on
photorefractive four-wave mixing in a ring cavity and its use as a new optical gyroscope. We …
