Paper Abstract

We present an overview of our theoretical studies on laser- induced damage (LID) in transparent optical materials including recent results on a pulsewidth dependence of the LID threshold, thermoelastic stress-induced damage criteria, damage morphology features, peculiarities of the LID at ultrashort pulse irradiation. Main attention is focused on inclusion-initiated damage, but some results are related also to intrinsic damage mechanisms. Theoretical results are compared with available experimental data on pulsewidth dependence of the LID threshold in bulk optical materials, on damage feature in thin films and on damage morphology studies. A good agreement of theoretically predicted and observed features is demonstrated, in particular, for the pulsewidth dependence of the LID threshold in a wide pulsewidth range from nanoseconds to femtoseconds.
