A recently predicted resonant effect for the enhancement of two-wave mixing in
photorefractive materials is investigated. The resonance occurs when the frequency of the …

A theoretical analysis is presented of two-wave mixing in photorefractive materials in which
the complex amplitude of a weak signal beam has slowly varying but otherwise arbitrary …

The recent study of nonlinear optical properties of photorefractive materials has led to the
experimental observation of anisotropic energy transfer in two-wave mixing, l the …

An amplification mechanism relying mainly on the real part of the arising space charge field
in the presence of two strong pump beams is described. The dependence of amplification on …

We apply directly a perturbative expansion to the hopping model of Feinberg. The first three
harmonics of the space‐charge field are presented, considering the contributions from the …

In the twenty years since the discovery of the photorefractive effect [4.1], it has proven to be
both a nuisance and an asset to the optics community. Originally, it was labelled" optical …

An expression for the gain in photorefractive two-wave mixing when radio-frequency (rf)
electric fields are applied to the material has been derived and compared with experiments …
