Dual-wavelength stimulated emission from a double-layer CdHgTe heterostructure optically pumped by a pulsed Nd:YAG laser at temperatures T = 77-150 K is reported. The emission spectral lines have been observed at wavelengths λ ∼ 2 μm and λ ∼ 3 μm. Emission spectra recorded at different temperatures are presented.
