The self-action of femtosecond optical vortices in LiF crystal at wavelength 1800 nm in the range of anomalous group velocity dispersion is considered. The influence of the topological charge on the spatio-temporal dynamics of the pulse and peak intensity values in the formation of ring light bullets is analyzed.
