The thermal and optical stability of photorefractive holograms written in iron-doped LiNbO 3
have been measured over the temperature range from 50 to 165 degrees C. In each case …

The fast time constants of holographic contrast growth and erasure for various
photorefractive polymer composites were measured under a wide range of experimental …

We write and read a refractive-index grating in a photorefractive crystal BaTiO_3 with a
single 20-nsec laser pulse at 532 nm. The grating formed is erasable with similar pulses …

By combining the band-transport equations with the coupled wave equations, we obtain a
self-consistent set of equations governing the recording of photorefractive holograms. Using …

We investigate the resonant two-photon (two-step) processes of photorefractive grating
formation and identify the regimes in which nonvolatile holographyis possible. We develop a …

The process of high-gain image amplification in photorefractive crystals is investigated. We
show that in the regime of large energy transfer, the spatially nonuniform depletion of the …

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 …

Abstract In a recent Letter,[1] Yeh presents a derivation of the response time of a
photorefractive material and asserts that this response time is a fundamental limiting value …

The effect of an imposed step-like phase-shift of the light fringes on the recording and
erasure kinetics of photorefractive gratings has been theoretically investigated for an …

The photorefractive recording process as described by Kukhtarev's material equations is
investigated for large modulation depths. We find that for modulation 1 the density ND+ of …
