Recording angularly multiplexed holograms in photorefractive media requires an
understanding of both the recording and erasure dynamics. In this paper a coupled‐wave …

Photoinduced light scattering is a serious drawback that limits the applicability of thick
holographic recording media but provides valuable information on the recording medium. As …

FIG. 2, Logarithm of the diffraction efficiency (relative values) of the rt'-vca! ed grating at 0· C
as a function of the readout time. The decay during the initial and the final stages is …

In this note attention is given to the holographic characterization of photorefractive sensitivity
by the spatial light modulation dependence in a Bi 12 TiO 20 crystal. A sample in the …

An analytical solution of the light‐induced decay of the photorefractive gratings from the
charge transport equations with shallow and deep traps is presented. It is predicted that the …

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 …

This work presents a holographic method based on active feedback techniques for
determining the sign of the dominant charge carriers in photorefractive materials. A two-step …

Extensive study of photorefractive polymeric composites photosensitized with semiconductor
nanocrystals has yielded data indicating that the inclusion of such nanocrystals enhances …

In this paper, the fundamental characteristics of the photorefractive effect, both in bulk
crystals and waveguides, as well as some of the most important photorefractive materials …

Two-step excitation processes have been used for hologram storage in photorefractive
crystals. By this means the interference pattern can be formed with red or near—IR light and …
