Photorefractive crystals such as BaTiO 3, Sr x Ba 1− x Nb 2 O 6 (SBN), and Bi 12 SiO 20 (BSO) are by far the most efficient media for the generation of phase-conjugated optical …

Using photorefractive two-wave mixing in a strontium barium niobate (SrxBa_1− xNb_2O_6) crystal in conjunction with a self-pumped barium titanate (BaTiO_3) phase conjugator, we …

We have characterized the photorefractive performance of a special 45°-cut crystal of BaTiO_3 and compared it with the conventional 0°-cut material. An increased peak gain …
We investigate the mutually pumped phase-conjugation process in photorefractive media with partially coherent pump beams. We consider the effects of transmission, reflection, and …

The generation of multiple waves during near-oblique incidence of a 532 nm weakly focused beam on photorefractive iron-doped lithium niobate in a typical reflection geometry …
Photorefractive self-pumped phase-conjugation is examined at near-infrared wavelengths using doped 'blue'BaTiO 3, and reflectivities are reported as high as 76% between 720 nm …
Experimental results are presented showing both cancellation and enhancement of the specular reflection off a partially transparent ordinary plane mirror in the presence of a …
