The transition from regular static patterns observed in optical systems to spatio-temporal chaotic regimes is not yet well understood. We address this problem in a ring cavity filled with a nonlinear self-focusing Kerr medium pumped by an external field. In the mean-field approximation the transverse dynamics of the slowly varying electric field amplitude E is governed by a driven-damped nonlinear Schroedinger equation.
