Abstract: The results of a qualitative analysis of a semiclassical model of radiation generation in solid-state lasers and, based on it, a numerical simulation of the regime of regular pulsations arising under conditions of nonlinear drift and broadening of the resonance gain line due to the influence of near fields of dipoles and absorption in quasi-resonant transitions on the dielectric susceptibility of an active medium are presented. Modeling was carried out for the parameters of semiconductor quantum-dimensional structures.

Keywords: lasing self-sustaining pulsations, nonlinear amplification, quasicrystal of quantum dots, dipole-dipole interaction.
