Photorefractive materials combine photoconductive and electro-optic properties: light affects
their electrical conductivity; their optical properties (refractive index, etc.) are affected by …

A numerical approach has been developed for simulating the recording and erasure kinetics
in photorefractive materials for high modulation of the light-intensity pattern. The recording …

The time evolution of the charge carrier density, ionized donor density and space‐charge
field under a sinusoidal light pattern have been calculated by solving numerically the …

A general approach to photorefractive kinetics, based on the band-transport model, has
been developed for nonphotovoltaic materials in the diffusion regime. For small grating …

An analytical solution of the photoconductive material equations for dynamic holographic
gratings of arbitrary contrast has been obtained. A method of measuring high-contrast …

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 …

We investigate experimentally and theoretically the dependence of the amplitude of the
spatial fundamental grating, created by a pair of coherent light beams while using the …

The analytic expressions for the first three higher-order harmonics of the space-charge field
versus time are obtained by use of the hopping model of Feinberg [J. Appl. Phys. 51, 1297 …
