It is shown that spatial gratings in photorefractive crystals, induced by the standing
interference pattern of two coherent waves and an external alternating electric field, may be …

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 …

We show analytically and numerically that the refractive-index gratings produced by the
photorefractive effect need not be of the same periodicity as the driving light intensity. Even …

The spatial subharmonic instability arising from the material equations is investigated
theoretically for both square and sinusoidal applied alternating electric fields. The threshold …

The modulational instability of quasi-plane-wave optical beams in biased photorefractive
media is investigated under steady-state conditions. The spatial growth rate of the sideband …

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 …
