Popis:	Stimulated emission based on interband transitions depending on the pumping wavelength is studied for heterostructures with Hg(Cd)Te/CdHgTe quantum wells in the wavelength region of 3–4 μm. The minimal value of the threshold power density and maximal temperature, at which it is possible to generate stimulated emission, correspond to energies of the pumping quantum near the barrier band-gap width. Structural broadening of the emission spectra is found for the structure with a coating layer of 150 nm in thickness under continuous pumping and at temperatures above 200 K. This broadening is associated with manifestation of the Stark effect, which appears due to the influence of the electric field of the space-charge region of the surface barrier.
