| We have studied the stability properties of nonlinear Bessel vortices in self-focusing Kerr media with nonlinear absorption. Nonlinear Bessel vortices are propagation-invariant solutions of the nonlinear Schrödinger equation with cubic nonlinearity and nonlinear absorption. We have found that these vortices can be stable against perturbations, including the azimuthal perturbations that usually break the cylindrical symmetry of standard vortex solitons in self-focusing Kerr media. This property is seen to arise from the stabilizing effect of nonlinear absorption. | |
