Recent analytical results in the frame of photorefractive spatial-soliton propagation are
exploited to derive a novel scheme for the investigation of space-charge field formation in …

The fundamental component of the space-charge field in a photorefractive crystal is studied
in the presence of an applied alternating electric field. A general equation for the amplitude …

Two-wave mixing of phase-modulated beams in photorefractive crystals under a dc electric
field is studied both theoretically and experimentally. Based on the vectorial theory of light …

Space-charge fields in photorefractive materials enhanced by moving fringes are studied for
simultaneous electron–hole transport. Two distinct models, one with a single set of impurity …

A theory of rectifying electric fields associated with photorefractive waves is presented. The
rectification effect is caused by scattering of photorefractive waves from the static grating of a …

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 …

It is shown that weakly damped space-charge waves exist in photorefractive crystals with a
sufficiently large lifetime–mobility product. The dispersion law, the damping constant, and …

An alternative empirical correction function is presented for the space-charge field of the
form ƒ (m)= m/(1+ bm), which simulates the functional form of ƒ (m)=[1− exp (-am)]/a …

We show, theoretically and experimentally, that the buildup of the space-charge field in
photorefractive crystals is far from monoexponential for circular light beams. This is a …
