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 …

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 report measurements of the holographic diffraction efficiency (HDE) of single
photorefractive gratings fixed by an externally applied voltage pulse in Sr0. 75Ba0 …

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 …

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 …

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 …

Beam coupling gain and response time together with reflectivity and response time of an
external ring phase-conjugate mirror are studied as a function of temperature for a crystal of …

We report what we believe to be the first observation of photorefractive gratings in lead
barium niobate (Pb_1-xBa_xNb_2O_6; PBN).? A diffraction efficiency of 9% and a beam …

An investigation was made of the photoelectric and photorefractive properties of barium
strontium niobate crystals having the composition (Sr x Ba 1–x) 1–y (Nb 2 O 6) y where x …

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 …
