We propose a mathematical model for the movement in absorbing materials of
photorefractive holograms under feedback constraints. We use this model to analyze the …

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

The coupling kinetics of a reflection-type photorefractive hologram are studied, and we have
found that the coupling between the adjacent channels increases as the reading time is …

We explore, theoretically and experimentally, the effects of self-enhancement (or self-
depletion) of the diffraction which occurs during coherent reconstruction from fixed …

Photorefractive materials have been extensively used in recent years as real-time recording
media for optical holography.[1],[2] One prospective application of real-time holography is in …

Holographic gratings are recorded and thermally fixed in iron-doped photorefractive lithium-
niobate crystals. A spatially modulated concentration of filled and empty electron traps (Fe …

The recording mechanism of the inner anisotropic holographic scattering cone in
photorefractive crystals is revealed. There are no experimental indications for our crystals …

Optical storage of information offers great potential for high capacity and speed. A very
promising approach to the embodiment of an optical memory is based on volume storage in …

An oscillatory characteristic of diffraction is observed as a result of strong beam coupling in a
weakly oxidized LiNbO_3: Ce: Cu crystal during the recording step in the production of …

In holographic experiments many photorefractive crystals show refractive-index changes
much smaller than one would expect from the known electro-optic coefficients and space …
