Description
Summary:The experimental observation of stimulated radiation of optically pumped Cd x Hg 1-x Te structures in the wavelength range of 1.4 - 4.5 mum is reported. In the experiments, graded-gap Cd x Hg 1-x Te samples grown on GaAs and Si substrates by molecular beam epitaxy were used. Superluminescence of such structures was observed at 77 - 300 K under the pulsed pumping of the samples by a Nd:YAG laser at a wavelength of 1.064 mum. At room temperature, stimulated radiation was observed at wavelength of 1.4 - 1.7 mum. The obtained experimental data are the first results on the observation of stimulated radiation from graded-gap Cd x Hg 1-x Te structures on Si and GaAs substrates at these wavelengths at room temperature.
