Abstract:
The experimental data on observation of spontaneous and stimulated emission from thin epitaxial CdxHg1?x Te films optically pumped by Nd: YAG laser radiation are reported. A simple theoretical model is suggested to describe the initiation of population inversion under these conditions. The parameters realized under the experimental conditions are theoretically estimated.
