Optimization of CdxHg1−xTe laser structures and stimulated emission at room temperature under optical excitation

Abstract

The main requirements for the MCT (CdxHg1−xTe) structures optimization for increase of the stimulated emission wavelength under optical pumping are discussed. The stimulated emission at wavelengths 2–2.5 µm at room temperature from optimized MCT structures is observed experimentally. The obtained experimental data are the first observation of stimulated emission from the MCT structures at these wavelengths at room temperature.
