title: Generation of multicolor spatial solitons by stimulated Raman scattering.
abstract: We report the experimental observation of Raman spatial solitons in a nonlinear planar waveguide. We show that, under certain conditions, stimulated Raman scattering (SRS) can stabilize the pump beam propagation and give rise to multifrequency spatial solitons. We present the different Kerr media with which we obtained self-focusing and SRS. The observations can be described in terms of Raman gain versus soliton power.
