An experimental investigation of the geometry of a double phase-conjugate mirror in a
photorefractive strontium barium niobate crystal is carried out. A shift of the transverse …

We describe the experimental measurement of phase-conjugate reflectivity versus various
ratios of input-beam intensities in photorefractive barium titanate and strontium barium …

The development of a theory of four-wave mixing in photo-refractive crystals is described.
This theory is solved in the undepleted pumps approximation with linear absorption and …

A new mutually pumped phase conjugator with a photorefractive copper-doped potassium
sodium strontium barium niobate crystal is demonstrated, in which the beams travel along a …

Theoretical considerations and experimental results are presented for simultaneous
degenerate multi-wave mixing in photorefractive BSO. Using the same crystal volume and …

The coupled wave equations for four-wave mixing (FWM) in a cubic, non-optically-active
photorefractive crystal are solved for the case of orthogonally polarized pumping beams. For …

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 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 …

Experimental results are reported for four-wave mixing at 633 nm with a photorefractive
Bi_12TiO_20 crystal in a double phase-conjugate mirror geometry. Recording in the …

Combined effects of cross and parallel coupling have been investigated in the case of
contradirectional two-wave mixing in an absorbing photorefractive crystal. Nonlinear …
