Abstract: The parameters of an optically pumped stripe waveguide laser based on an HgCdTe heterostructure with quantum wells for single-mode generation of radiation in the wavelength range of 25–41 $\mu$m are optimized. It was shown that the width of the ridge should not exceed 15 $\mu$m to implement single-mode generation in a laser with an etching depth covering the active region.

Keywords: laser, waveguide, mode, HgCdTe, far-infrared region.
