    Abstract

    The stable propagation of spatially localized optical vortices in self-focusing nonlinear media was investigated. The optical vortices were created by partially incoherent light beams which propagated in a photorefractive nonlinear medium and carried a phase dislocation. The single-charge and double-charge optical vortices were stabilized in self-focusing nonlinear media when the value of the spatial incoherence of light exceeded a certain threshold. The results show that the vortex stabilization was confirmed by numerical simulations and was also applied to higher-order vortices.
