Observation of azimuthal modulational instability and formation of patterns of optical solitons in a quadratic nonlinear crystal.

We report what is believed to be the first experimental demonstration of the azimuthal self-breaking of intense beams containing a vortex phase dislocation into sets of optical spatial solitons in a quadratic nonlinear material. The observations were performed in a KTP crystal.
