Physical mechanisms of formation of radiation losses in the terahertz range in ZnGeP2 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.
