Two emission bands are observed in GaSe under N 2 laser excitation at 77K and 4.2K. The spectral band shapes agree with theoretical curves for an exciton-electron and an exciton-exciton collision processes. Stimulated emission is ascribed to the exciton-exciton collision process. Red shift of the stimulated emission line is explained by reverse absorption of this process.
