Abstract: Based on the numerical solution to the semiclassical Maxwell–Bloch equations in a one-dimensional model of a superradiant laser with a low-Q symmetric Fabry–Perot cavity, a comparative analysis of the spectrum of polariton modes of the linearized problem and the discrete spectrum of the of quasimonochromatic generation with weak self-modulation under the condition of strong spontaneous mirror symmetry breaking of the counterpropagating electromagnetic waves, population inversion and polarization of an active medium is carried out. It is shown that the main frequencies of resonant self-modulation of a steady asymmetric superradiant phase state are close to the frequencies of polariton modes that are calculated in the linearized problem for the average level of the population inversion taken from the nonlinear problem and have small decay rates.

Keywords: superradiant phase transition, polariton modes, heterolaser, self-modulation regime, discrete spectrum, low-Q cavity.
