title: Observation of vortex solitons created by the instability of dark soliton stripes.
abstract: The first experimental observation to the authors' knowledge is reported of the generation of optical vortex solitons from instability and breakup of a dark soliton stripe propagating through a saturable self-defocusing nonlinear medium.
