Abstract
Thresholds for damage to the surfaces of infrared laser optical materials by intense 0.5 µsec pulses of CO2 laser radiation have been measured. Very tentative values obtained for NaCl window material ranged from a low of 10 MW/sq. cm for coated surfaces to a high of 30 MW/sq. cm for uncoated cleaved surfaces. The experimental difficulties encountered are discussed with a view to obtaining improved data in future, more extensive experiments.
