Investigation of the Process of Optical Damage of ZnGeP2 Crystals Using Digital Holography

A method of visualization of the process of optical damage of a ZnGeP 2 single crystal using digital holography is suggested. The mechanism of the ZnGeP 2 single crystal damage is investigated at energy density ~0.3–0.6 J/cm 2 . The temperature in the damage channel during its formation is estimated...

Description
Summary:A method of visualization of the process of optical damage of a ZnGeP 2 single crystal using digital holography is suggested. The mechanism of the ZnGeP 2 single crystal damage is investigated at energy density ~0.3–0.6 J/cm 2 . The temperature in the damage channel during its formation is estimated. The data obtained allow the conclusion on the thermal nature of ZnGeP 2 crystal damage to be made under the action of laser radiation with a wavelength of ~2.1 μm.
