CW CO2Laser Induced Damage to Infrared Window Materials
CW CO2 laser induced damage to several kinds of infrared window materials has been investigated. It has shown that the damage mechanism is attributed to thermal shock stress caused by the absorption of impurities and defects in the materials. We have established a model concerning the defect intensity and focus spot with damage threshold, and the damage modes of thermal shock stress are analyzed.
