Mechanism for photorefractive phase conjugation using incoherent beams

MD Ewbank - Optics letters, 1988 - opg.optica.org
Two mutually incoherent extraordinary laser beams, incident upon opposite a faces of a
BaTiO_3 crystal, generate a set of photorefractive holograms that channel both beams …

Laser beam self-focusing in photorefractive materials: optical limiting application

D Wolfersberger, N Fressengeas, J Maufoy… - Journal of Nonlinear …, 2000 - World Scientific
This paper presents a way to achieve optical limiting using the self-focusing of a laser beam
in a photorefractive medium. In this view, the protection is not based on the absorption of the …

Steady-state vortex-screening solitons formed in biased photorefractive media

Z Chen, M Shih, M Segev, DW Wilson, RE Muller… - Optics letters, 1997 - opg.optica.org
We report the observation of steady-state photorefractive vortex-screening solitons. As a
singly charged circular vortex nested on a broad beam propagates through a biased …

Observation of bright spatial photorefractive solitons in a planar strontium barium niobate waveguide

D Kip, M Wesner, V Shandarov, P Moretti - Optics letters, 1998 - opg.optica.org
We have obtained stationary bright spatial solitons in a planar photorefractive strontium
barium niobate waveguide for visible light ranging from 514.5 to 780?? nm. Even for larger …

Anisotropic scattering in photorefractive crystals

DA Temple, C Warde - JOSA B, 1986 - opg.optica.org
A well-defined ring of anisotropically scattered light is observed when a linearly polarized
laser beam is incident upon a birefringent photorefractive crystal such as BaTiO_3 …

Optically induced transition between discrete and gap solitons in a nonconventionally biased photorefractive crystal

P Zhang, S Liu, J Zhao, C Lou, J Xu, Z Chen - Optics letters, 2008 - opg.optica.org
We show that optically induced photonic lattices in a nonconventionally biased
photorefractive crystal can support the formation of discrete and gap solitons owing to a …

Spiraling behavior of photorefractive screening solitons

MR Belić, A Stepken, F Kaiser - Physical review letters, 1999 - APS
The question of spiraling or no spiraling of incoherent screening spatial solitons in
photorefractive crystals is addressed by a careful numerical analysis. We find that the …

Annihilation of photorefractive solitons

W Królikowski, B Luther-Davies, C Denz, T Tschudi - Optics letters, 1998 - opg.optica.org
We investigate experimentally the interaction of two-dimensional solitary beams in
photorefractive strontium barium niobate crystal. We show that simultaneous collision of …
