    "abstract": "Nonlinear losses accompanying Kerr self-focusing substantially impacts the\ndynamic balance of diffraction and nonlinearity, permitting the existence of\nlocalized and stationary solutions of the 2D+1 nonlinear Schrodinger equation\nwhich are stable against radial collapse. These are featured by linear conical\ntails that continually refill the nonlinear, central spot. An experiment shows\nthat the discovered solution behaves as strong attractor for the self-focusing\ndynamics in Kerr media.",
