Abstract : We present here a spatial instability, free from longitudinal feedback, in which a beam propagating in one direction in a self-focusing medium breaks up into more and more filaments as the input power is increased. These cell-exit patterns (solitary waves) are stable and highly reproducible, showing that they are seeded by fixed phase variations across the input profile and not by random fluctuations. The physics of the formation of the solitary waves is the competition between self-focusing and diffraction leading to the eigenmodes of propagation, to the solitary-wave solutions of nonlinear Schrodinger-type equations.
