We have confirmed that photorefractive Bi 12 TiO 20 (BTO) crystal has incongruent melting
properties and the upper limit for growing BTO single crystals is found to be 11 mol% TiO 2 …

Another optical nonlinear effect is reported: the transient self-bending of a laser beam within
a photorefractive crystal under an external electric field. It is based on the large drift length of …

We report on the experimental evidence of the light intensity dependence of the Debye
screening length ls in undoped photorefractive titanosillenite crystals (⁠ Bi 12 TiO 20⁠) by …

Reduced KNb01 crystals are shown to have the fastest photorefractive response times for
applications in the visible wavelength region. Grating build-up times at cw illumination in the …

Real-time direct measurement of the amplitude and the phase of photorefractive fields is
performed for all stages of photorefractive grating formation including saturation. The …

Recent developments, both theoretical and experimental, involving the nonlinear
