In the linear response regime close to equilibrium, the fluctuation-dissipation theorem
relates linear transport coefficients via the well-known Green–Kubo or Einstein relation. The …

Phenomena that accompany optical excitation of eigenmodes of electron gas oscillation in
semiconductors with an N-shaped current-voltage (IU) characteristic in a strong electric field …

We investigate the dispersion law (relationship between Ω k and K) of photorefractive waves
using a new experimental method based on the excitation of photorefractive waves by a …

A new phenomenon associated with a nonlinear interaction of optically excited space
charge waves has been discovered in photorefractive crystals of the sillenite family. This …

This paper consists of two parts. The first contains a short review of the main characteristics
and holographic phenomena typical of sillenites, and the second part is devoted to new …

A theory explaining the effects of second harmonic generation and rectification of space-
charge waves (SCWs) in both space and time in photorefractive crystals and semi-insulating …

During holographic recording in photorefractive crystals (BSO, BGO, and BTO) by an
oscillating interference pattern we observe a strong dynamic deflection of the laser beams …

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 …

For the first time the effects of overall doubling, spatial doubling, and overall rectification of
space charge waves in a photorefractive crystal (Bi 12 GeO 20, BGO) have been detected …

A new approach for studying photorefractive gratings in two-wave mixing experiments by a
phase modulation technique is presented. The introduction of a large-amplitude, high …
