In investigations of build-up and decay of elementary holograms in Bi12Ti0. 76V0. 24O20
(BTVO) crystals, non-exponential dynamics is observed. In combination with measurements …

The results of theoretical and experimental studies of the photorefractive effect in two
different classes of materials--perovskite BaTiO 3 and tungsten bronze SBN--have been …

Experimental results on self-diffraction of periodically phase-modulated laser beams from a
relief grating formed on a free surface of a cubic photorefractive Bi12TiO20 crystal due to the …

A method to characterize the photorefractive parameters of Bi 12 GeO 20 crystal is
described. An analysis of the transient photoinduced grating under an external applied …

We present concrete evidence for the formation of ferroelectric domain gratings induced by
photorefractive space-charge electric fields in top-seeded solution-grown barium titanate …

We present data showing a nonlinear photorefractive response at high modulation depths in
a Bi_12TiO_20 sample when applied ac fields are used. The data are interpreted by means …

Nonlinear refraction, nonlinear absorption and optical limiting in photorefractive crystals Bi
12 SiO 20 (BSO) and Bi 12 GeO 20 (BGO) at the wavelengths of 1064 and 532 nm were …

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 …

The large optical nonlinearities of many photorefractive crystais, which can be induced by
moderate light intensities, were the prosperous ground for intensive and diverse activities. I …
