Abstract: Physical mechanisms of formation of radiation losses in the terahertz range in ZnGeP$_2$ crystals have been experimentally studied in the wave number range of 5–350 cm$^{-1}$ at temperatures of 10–300 K. The dominant contribution of two-phonon difference processes to the loss formation in the given frequency range has been shown.
