Abstract: The results of a theoretical study of THz radiation generation at a difference frequency in a HgTe/HgCdTe quantum-well laser are presented. It is shown that in such a laser having a waveguide width of 100 μm, at the power 1 W of the near-IR radiation modes the radiation power at the difference frequency in the range 0.5–3.5 THz reaches 90 μW at room temperature.

Keywords: laser, THz frequency range, difference frequency.
