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 …

It is shown that a moving intensity grating in a photorefractive crystal with a sufficiently large
lifetimemobility product can give rise to an instability against excitation of weakly damped …

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 …

The conditions for the existence and the main characteristics of weakly damped space-
charge waves are investigated for photorefractive ferroelectrics. These conditions are …

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 …

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 space-charge-field formation in a photorefractive crystal illuminated by a one-
dimensional light pattern is studied when an alternating square-wave electric field is applied …

We investigate experimentally the fundamental characteristics of space-charge waves
excited in a photorefractive crystal of Bi_12SiO_20. Features such as their transient rise and …
