Experimental data show that the dominant light amplification channel, responsible for the development of lasing in CuBr crystals and consequently for the appearance of new bands in their luminescence spectra during intense single-photon excitation at temperatures of 4.2–300 K, involves stimulated processes which accompany inelastic exciton–electron interactions.
