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 …

We numerically studied the spatial fidelity of coherent image amplification by two-wave
mixing configurations in photorefractive BaTiO_3: Ce using a three-dimensional analysis …

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 …

We present experimental results showing the partial cancellation of the specular reflection
off a partially transmitting ordinary plane mirror in the presence of a phase-conjugate mirror …

We demonstrate a new method of light amplification based on forward four-wave mixing in
photorefractive BaTiO_ 3. A single pump beam of combined (ordinary and extraordinary) …

Expressions of the coupling constant for contradirectional two-wave mixing (CTWM) have
been derived. The calculations show that the energy transfer in CTWM has some unique …

Beam-coupling experiments are carried out with two BaTiO_3 crystals as a function of the
intensity and wavelength. We demonstrate in these experiments that hole–electron …

The gain–length product for two-wave mixing in photorefractive BaTiO_3 is calculated as a
function of the angles between a pump beam and a scattered beam and the crystal c axis …

We propose and analyze a new type of phase conjugation between counterpropagating
beams in photorefractive materials based on diffraction from transmission gratings only. This …
