We report the use ofCe-doped Srx Bal _ x NbzO (" X= 0.60 and 0.75, as the holographic
fourwave mixing medium in the construction of a self-starting passive phase conjugate …

We treat the photorefractive effect in oxide crystals at elevated temperatures where charge
compensation occurs in the absence of photoexcitation of the compensating species. These …

In this article, we studied the photorefractive properties of Cu-doped (K 0.5 Na 0.5) 0.2 (Sr
0.75 Ba 0.25) 0.9 Nb 2 O 6 (Cu: KNSBN) crystals with different doping levels. The properties …

We show that high-temperature reduction in a CO–CO_2 atmosphere increases the
photorefractive sensitivity of KNbO_3: Rh at 860?? nm by 4 orders of magnitude compared …

We present here the experimental results of photorefractive two-wave coupling in the
congruent strontium barium niobate (SBN: 61) crystal doped with 1000ppm Cr. Employing a …

Vanadium and magnesium co-doped LiNbO 3 (LN) crystals were grown, and their
photorefractive properties were studied in the visible spectral region. At 488 nm the shortest …

In this note attention is given to the holographic characterization of photorefractive sensitivity
by the spatial light modulation dependence in a Bi 12 TiO 20 crystal. A sample in the …

We experimentally demonstrate the possibility of photorefractive 2D self-focusing in bulk
Cerium doped Strontium Barium Niobate (SBN: Ce) directly at telecommunications …

We present the results of experimental study of the absorption coefficient, two-beam
photorefractive coupling constant, and photorefractive response time of a doubly Ce-and …

Strontium barium niobate (SBN) was doped with rhodium to enhance its photorefractive
behavior. Crystals with six different Rh concentrations, ranging from 0.015 to 0.20 wt …
