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 …

The diffraction efficiency of volume gratings written by two-wave mixing in a cerium-doped
potassium sodium strontium barium niobate (Ce: KNSBN) photorefractive crystal is studied …

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 …

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 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 …

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 …

A series of LiNbO3 crystals doped with various concentrations of ZnO and fixed
concentrations of RuO2 and Fe2O3 have been grown by the Czochralski method from the …

The photorefractive effect is demonstrated in single crystals of ferroelectric Ce-doped (BaSr)
_6Ti_2Nb_8O_30 for the first time to our knowledge. The maximum intensity gain, measured …

We characterize the holographic storage characteristics of photorefractive SBN: 60 (Sr 0.6
Ba 0.4 Nb 2 O 6) under an externally applied electric field. The field dependence of the …

Tetragonal lead barium niobate Pb_1–xBa_xNb_2O_6; 1-x< 0.63 crystals are promising
photorefractive materials for applications such as holographic data storage. Measurements …
