Generation of soliton packets in a two-level laser

  • A. A. Zabolotskii
Nonlinear Physics


A variant of perturbation theory is constructed for a system of nearly integrable equations. Perturbations of a special type are considered, which makes it possible to represent the system in the form of compatibility condition for “deformed” linear systems. The corresponding deformation of the Whitham equations is found. The mathematical apparatus is used to theoretically examine the generation of a sequence of solitons in a two-level laser. The generation process is described by a system of Maxwell-Bloch equations with pumping of the upper level and with allowance for some relaxation effects. The dynamics of the transformation of the initial perturbation into a sequence of solitons under pumping is studied. Finally, the various generation regimes are analyzed and compared with the experimental data.
