Abstract
The stimulated emission from CdSe at 80 K has been studied as depending on the excitation intensity, the excited length of the sample and the wavelength of the pumping laser. The optical gain has been measured as a function of the emission wavelength. It is shown that the stimulated emission from CdSe under strong optical pumping can be ascribed to two different radiative mechanisms involving the exciton-exciton interaction process and, at very high excitation level, the electron-hole plasma recombination.Keywords
