The temporal and spatial variation of the beam intensities and space charge electric field
during hologram formation in a photorefractive crystal are determined by solving the relevant …

The process of hologram recording in a photorefractive crystal in an external dc field is
considered from the point of view of material equations. Conditions are calculated for the …

The partial differential equations of Kukhtarev et al.(1977) which describe the time
dependence of hologram formation in photorefractive materials are solved analytically in the …

The theoretical analysis of unstationary holographic recording in photorefractive crystals
under an external alternating electric field is presented. In particular, a step-like ac field …

Theoretical and experimental studies of the interaction of two counterpropagating light
waves on dynamic reflection gratings formed in the Denisyuk scheme in cubic …

We explore theoretically and experimentally how application of an electric field to a
photorefractive crystal affects the recording and the readout of holograms. We consider, for …

We present a very simple solution to the coupled partial differential equations which
describe the time dependence of hologram formation in photorefractive materials. The …

A mechanism for recording a static hologram in photorefractive Bi_12TiO_20 crystal by a

The paper analyzes the nonlinear recording and obliteration of holographic gratings in
electro-optical crystals, with consideration of the interaction of the grating and the light wave …

Oscillating behaviour of diffracted light on uniform illumination of holograms, recorded in
photorefractive crystals Bi 12 TiO 20, is observed experimentally. From the experimental …
