We demonstrate selective fixing of volume holograms in photorefractive media. Each
holographic page may be fixed individually and overwritten without destroying the other …

Photorefractive holograms stored in Sr_0. 75Ba_0. 25Nb_2O_6 crystals are electrically fixed
at room temperature. The fixed holograms can be read out directly or after a positive-voltage …

Holographic gratings are written in photorefractive Sr_0. 61Ba_0. 39Nb_2O_6 crystals by
two interfering light beams. Angular-dependent readout of the holograms shows that …

We demonstrate that holographic recording in photorefractive materials can be improved by
using a moving grating to reduce energy coupling. In cerium-doped Sr_0. 6Ba_0 …

We demonstrate a new fixing method with SrxBa_1− xNb_2O_6 crystals. This is done by
inducing ferroelectric domains in the crystal in real time, by a screening mechanism. Images …

We demonstrate holographic fixing by means of a thermal cycling procedure in pure and
doped photorefractive KNbO_3 crystals. At elevated temperatures (70–100° C) the …

We report the use of actively stabilized holographic recording in high-diffraction-efficiency
crystals in which strong energy coupling occurs. We use this technique to characterize the …

We demonstrate superior holographic storage performance in a cobalt doped potassium
sodium strontium barium niobate (Co: KNSBN) crystal that possesses a fast response time of …

We investigate an incremental recording technique for multiplexed hologram storage in
photorefractive crystals, in which each hologram is recorded with multiple short exposures …

We report experimental results that demonstrate for the first time, to our knowledge, more
than 20 holograms stored and recalled with equal diffraction efficiency in photorefractive …
