Abstract
Usual dissipative vortex solitons in the complex Ginzburg-Landau (CGL) model are supported by a balance between diffraction, self-focusing, losses and gain. Lifting the restriction of strong transversal localization, we have found stationary Bessel-vortex states in the nonlinear Schrödinger model with added dissipation supported by a balance between dissipation and an inward power flux from their intrinsic reservoir. With low dissipation and slow inward flux, these transverse patterns suffer from azimuthal instability, but high dissipation and fast restoring influx stabilize these weakly localized vortex-carrying structures. Similar results can readily obtained in the CGL model, where a three-fold balance between gain, losses and influx power can be given.
