Growth-induced striations in photorefractive media scatter transmitted light, degrading their
performance in holographic applications. We model this phenomenon by considering the …

Growth-induced striations in photorefractive media constitute phase gratings that scatter
transmitted light and therefore degrade the quality of reconstructed images in holographic …

We propose and analyze a new type of phase conjugation between counterpropagating
beams in photorefractive materials based on diffraction from transmission gratings only. This …

We consider the possibility of restoration and/or enhancement of decaying holograms in
photorefractive media by using a simple optical readout in conjunction with a phase …

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 …

Stimulated photorefractive backscattering produces a phase-conjugate wave under some
conditions. Numerical solutions to the time-dependent wave equation for the backscattered …

Theoretical and experimental studying of the vectorial wave mixing in the photorefractive
crystal in the reflection geometry without applying an external electric field is presented. We …

Photorefractive crystals are being used in a growing number of applications such as two-and
four-wave mixing, realtime holography, interferometry, and image processing.[1] Four-wave …

A mechanism for recording a static hologram in a photorefractive crystal in an externally
applied ac field is investigated. One beam is rapidly modulated, and the interference pattern …
