Abstract

The inclusion-dominated model of laser-induced damage is reexamined in light of recent mea- surements of thin film thermal conductivities. In particular, the effects of varying the thermal conductivity and imaginary part of the index of refraction are explored. Two different values of the index of refraction are shown to be associated with a given damage threshold, and physical mecha- nisms are proposed for each value. Thermal conductivity is demonstrated to affect only weakly the value of the imaginary part of the index of refraction corresponding to a particular damage threshold.
