We present for the first time, to our knowledge, a theoretical analysis of the nonlinear
dynamic space-charge field buildup when a photorefractive medium is exposed …

We present a theoretical investigation of the nonlinear phenomenon of spatial frequency
mixing in photorefractive materials. In particular, we study the kinetics of the second …

We develop the idea of critical enhancement of the photorefractive response near the
threshold of parametric excitation of space-charge waves (the spatial subharmonics) taking …

We analyze the stability against parametric excitation of space-charge waves of the space-
charge field induced in a semiconducting crystal by a traveling light grating. We show that …

Аналитически и численно исследована фазовая часть системы уравнений,
описывающей двухволновое смешение в фоторефрактивной сильно инерционной …

This thesis deals with the fundamental photorefractive and photovoltaic properties of iron-
doped lithium niobate crystals. Experimental observations of a strong magnetic field effect …

Without using the usual assumption of free-carrier quasi-static distribution, we derive a
forced-oscillation equation with damping to describe the buildup of a fundamental harmonic …

Experimental observations on the structure of photorefractive subharmonic domains in Bi 12
SiO 2o (BSO) generated by a running intensity grating are described. The near field …
