Abstract

A new versatile CO² laser damage facility which uses a TEA laser giving a single mode output of up to 15 Joules per pulse is described. The temporal characteristics of the pulse can be readily varied. A method of producing pulses with durations less than that of the gain switched spike using plasma-based temporal attenuators is described. Data is presented on a range of infrared optical materials as well as commercial and experimental AR coatings and dielectric reflectors. Detailed examination of the damage morphologies coupled with the dependence of the damage threshold on pulse length is used to determine the mechanisms of laser induced damage.
