We study two heterostructures with an array of 10 HgCdTe/CdHgTe quantum wells, grown within a single technological series and designed to generate stimulated emission (SE) in the 20 – 30 µm wavelength range. In the more short-wavelength structure we obtain SE at the wavelength λ ~ 23.9 µm at 10 K, while no SE was obtained in the more long-wavelength structure. We calculate optical absorption in passive layers for both structures and show it to be higher in the more long-wavelength structure. Finally, we consider several ways to minimize absorption influence on SE generation.
