This paper presents a review of photorefractive effects in electro-optic materials and their
applications. Materials properties giving rise to increased photo-sensitivities are discussed …

Photorefractive materials have been assuming ever increasing prominence in the non-linear
optics field due to their unique capability for displaying strong non-linear effects at milliwatt …

Photorefractive materials combine photoconductive and electro-optic properties: light affects
their electrical conductivity; their optical properties (refractive index, etc.) are affected by …

Nonlinear optics has been a rapidly growing field in recent decades. It is based on the study
of effects and phenomena related to the interaction of intense coherent light radiation with …

This paper considers two effects for directly studying thick-phase holograms:(a) coupling
between the two laser beams used to record a hologram and (b) interference between a …

This paper describes the results of an investigation into techniques for obtaining erasure
resistant holograms in electro-optic crystals. The most successful approach made use of …

The optically induced change of the refractive index of electro-optic crystals, which was
discovered over ten years ago in LiNb03, is now referred to as the photorefractive effect (by …

We review the current status of the photorefractive tungsten bronze family crystals in terms of
their growth problems and applications, with special emphasis on the current results for the …

The properties of FeH, FeH, and other 3d n ionic impurities in the LiNbOJ structure are
investigated with a view to elucidating the mechanism of laser-induced reversible refractive …

In the field of optical data storage and processing, the main difficulty arises from the active
materials in which the information has to be written. For instance, silverhalide photographic …
