We report experimental and theoretical studies of nonvolatile photorefractive holographic
recording in LiNbO_3: Cu: Ce crystals with two illumination schemes:?(1) UV light for …

Dynamic coupled-wave theory predicts the bending of recorded hologram phase planes in
most photorefractive crystals. Bent holograms occur in LiNbO_3 and other photovoltaic …

Several methods are investigated to avoid undesired erasure during read-out of volume
phase holograms stored in photorefractive crystals. We present results on thermal fixing and …

We report the bleaching properties of iron and copper co-doped lithium niobate crystals that
are candidates for non-volatile holographic storage. In experiment, we propose a three-step …

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 …

Photochromic effect of lithium nioabate crystal doubly doped with Fe and Cu (LN: Fe: Cu)
was investigated for 532 nm wavelength illumination with the aim of nonvolatile holographic …

A 90° two-beam coupling configuration was used to store an image of an extended object in
a 0.032% wt iron-doped LiNbO3 crystal. A volume hologram was thus generated, via the …

We propose a novel technique to enhance a non-volatile photorefractive grating in a two-
color holographic recording. Resultant diffraction efficiency is increased by an applied …

A small photochromic grating is selectively and continuously detected from a much larger
photorefractive modulation in Fe-doped LiNbO3 crystals in a two-wave mixing experiment …

We present experimental data showing a significant dependence of light absorption on
temperature in photorefractive LiNbO 3: Fe crystals. The results are successfully explained …
