Photorefractive two-beam coupling with reduced spatiotemporal coherence

H Kong, C Wu, M Cronin-Golomb - Optics letters, 1991 - opg.optica.org
Photorefractive two-beam coupling with reduced spatiotemporal coherence is investigated
both theoretically and experimentally. Limited spatiotemporal coherence results in spatially …

Photorefractive two-beam coupling with light of partial spatiotemporal coherence

M Cronin-Golomb, H Kong, W Krolikowski - JOSA B, 1992 - opg.optica.org

studied theoretically and experimentally. Coupled-wave equations and a beam-propagation …

Feedback-controlled photorefractive two-beam coupling

VP Kamenov, KH Ringhofer, BI Sturman, J Frejlich - Physical Review A, 1997 - APS
We show that a certain phase feedback between output and input changes dramatically the
characteristics of photorefractive two-beam coupling. The diffraction efficiency of the …

Manipulating the information carried by an optical beam with reflexive photorefractive beam coupling

DZ Anderson, M Saffman, A Hermanns - JOSA B, 1995 - opg.optica.org
A two-beam coupling interaction of an information-bearing beam with a copy of itself in a
photorefractive medium changes the spatiotemporal nature of the beam. We analyze the …

Two-beam cross coupling from mutually incoherent lasers

D Statman, B Liby - JOSA B, 1989 - opg.optica.org
The cross coupling of two mutually incoherent sources in photorefractive materials is
described. It is shown that when there are two mutually incoherent pump beams that are not …

Phase conjugation involving incoherent counterpropagating beams in photorefractive media

M Segev, A Yariv - Optics letters, 1991 - opg.optica.org
We propose and analyze a new type of phase conjugation between counterpropagating
beams in photorefractive materials based on diffraction from transmission gratings only. This …

Signal-to-pump ratio dependence of buildup and decay rates in photorefractive nonlinear two-beam coupling

M Horowitz, R Daisy, B Fischer - JOSA B, 1992 - opg.optica.org
The buildup and the decay of photorefractive two-beam coupling are experimentally
demonstrated to be strongly dependent on the intensity ratio of the two beams (signal-to …

Analytical modeling of two beam coupling during grating translation in photorefractive media

HC Pedersen, PM Johansen, TG Pedersen - Optics communications, 2001 - Elsevier
We present two analytical methods of solving the coupled wave equations related to two-
wave mixing in a photorefractive medium in the case where the illuminating light pattern is …

Enhancement of the signal-to-background ratio in photorefractive two-wave mixing by mutually incoherent two-beam coupling

S Breugnot, M Defour, D Dolfi, H Rajbenbach… - Optics letters, 1994 - opg.optica.org
We present and experimentally demonstrate a new method for enhancing the signal-to-
background ratio of two-wave mixing in photorefractive crystals. The method uses a mutually …
