A method of visualization of the process of optical damage of a ZnGeP₂ single crystal using digital holography is suggested. The mechanism of the ZnGeP₂ single crystal damage is investigated at energy density ~0.3–0.6 J/cm². The temperature in the damage channel during its formation is estimated. The data obtained allow the conclusion on the thermal nature of ZnGeP₂ crystal damage to be made under the action of laser radiation with a wavelength of ~2.1 μm.
