Abstract

We have produced beams with dark rings and studied their propagation through photovoltaic photorefractive media. We observe that dark rings, instead of forming dark ring solitons, break into vortex–antivortex pairs, forming quadrupoles. The experimental results could be taken as a consequence of modulational instability during beam propagation that is revealed through our numerical analysis.
