Polariton Phenomena in Superradiant Lasing with a Low-Q Asymmetric Fabry–Perot Cavity

We study polariton phenomena and the mechanism of self-modulation of a highly asymmetric state of the active medium and field in a superradiant laser with a low-Q Fabry–Perot cavity based on the numerical solution of the semi-classical Maxwell—Bloch equations. Features of the predicted dissipative superradiant state arising due to the formation of an inhomogeneous self-consistent population-inversion grating, which is created by the beats of counterpropagating waves of the electromagnetic field and polarization of the active medium, are found. Evidence for excitation of polariton modes by resonant Rabi oscillations of active centers located near the maxima of the population inversion and polarization of the active medium is presented.
