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 …

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 …

We propose a theory of the instability of the space-charge field induced in a semiconductor
by the movement of light fringes against subharmonic generation. A crucial element of this …

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 …

We report a direct observation of space charge waves in photorefractive crystals with point
group 23 (sillenites) based on their penetration into an area with uniform light illumination. It …

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 …

A three-dimensional model describing two-wave mixing in photorefractive crystals with finite
beams of arbitrary shape is presented. The well-known longitudinal and transverse …

Holograms whose erase times are much longer than write times have been obtained in Bi $
iO, c (BSO) I3 and Bit2Ti02c (BTO). 4 This phenomenon has been attributed to the presence …

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 …
