Abstract

Laser autosolitons - localized spots of lasing in wide-aperture lasers with additional nonlinear losses - are characterized by hard excitation of lasing [1]. These spatial solitons are promising for optical information processing. They have unique properties with no analogues among spatial solitons in other optical systems. Laser autosolitons can have axially symmetric non-rotating or axially non-symmetric rotating distributions of intensity, and wavefront phase without screw dislocations or with dislocations of different orders (integer topological charge). The present communication gives results of our theoretical analysis and computer simulations of transverse motion of laser autosolitons in a limited cavity aperture.
