摘要
Stimulated emission at 6 K by optical excitation has been investigated in ZnSe epilayers. A detailed examination of the spectra below threshold indicates that the stimulated emission is due to inelastic exciton-exciton scattering, in contrast with some recent reports that lasing is due to electron-hole plasma luminescence modified by self-absorption. A red shift of the lasing line at high pump intensities has also been modeled in terms of the exciton-exciton and band filling mechanisms, giving excellent agreement with the data.
