Paper Abstract

Dynamical behavior of counterpropagating (CP) incoherent laser beams in photorefractive crystals is investigated. We perform experimental study displaying rich dynamics of three-dimensional CP optical solitons and formulate theory capable of capturing such dynamics. We find that our numerical simulations qualitatively agree with experimental findings for various CP beam structures. We also study numerically CP vortices in photorefractive crystals, in both space and time. The propagation of more complex CP beam arrangements, such as arrays of vortices, is also considered, and the transition from a few-beam propagation behavior to the transverse pattern formation dynamics is followed.
