Abstract

We describe one of the possible ways of development of a spatial instability of counterpropagating strong light beams in resonant media. The interplay between self-focusing and saturation effects results in a formation of counterpropagating stable filaments. The nondegenerate four-photon scattering in these waveguiding structures leads to a far-field multiconical emission with the cones' frequencies shifted to both red and blue sides of the resonant transition. \textcopyright{} 1996 The American Physical Society.
