The internal oscillation of localized optical vortex solitons (LOVS) in a cubic-quintic nonlinear medium is investigated in its stability parameter region. Internal modes both with and without angular dependence are found. The dynamics of LOVS perturbed by internal modes are simulated. Numerical res
A novel method is reported for calculating the nonlinear resonant change in refractive index of a doped saturable medium at the short-pulse excitation. The derived system of equations for energy density and phase of a short pulse propagating in the doped medium allows one to address a rather general
