Single‐crystal Sr0. 75Ba0. 25Nb2O6 when used in conjunction with an externally applied
electric field is shown to be a sensitive volume holographic medium capable of high …

80 100 120 140 TlME (sec) were then removed from the solidified melt. Chemical analysis of
the crystals showed O. 036-wt% Fe and 0.002-wt% Mo. The sample used for the tests was …

We characterize the performance of photorefractive Sr_0. 6Ba_0. 4Nb_2O_6 under an
externally applied voltage. We compared the field dependences of the gain coefficient …

High optical sensitivity is observed in 0.1 wt% Ce‐doped strontium barium niobate (SBN)
crystals in the absence of an external electric field. Only 5–10 mJ/cm2 of incident 0.488‐μm …

Single‐crystal lithium niobate has been used as a holographic storage medium. The
material undergoes a change in refractive indices upon exposure to suitably intense light …

The readout diffraction efficiency of a photorefractive hologram stored in single-crystal
strontium barium niobate (SBN) is shown to depend strongly on a uniform electric field …

Cerium‐ion‐doped barium‐strontium niobate crystals are considered as a medium for
information holographic recording. A brief account is given of the technology of crystal …

Holographic storage experiments using crystal Sr_0. 75Ba_0. 25Nb_2O_6 (SBN 75/25) as a
volume-phase holographic medium show that this material is the most sensitive crystalline …

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 …

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 …
