Paper Abstract

There are reviewed and summarized several theoretical models describing various mechanisms of developing of laser-induced temperature and field instabilities in both absorbing and nonabsorbing microinclusions. The key points are different mechanisms of positive feedbacks between laser-field and matter parameters connected with laser-induced variations of both refraction and absorption. Most attention is paid to application of the models to investigation of laser-induced damage of transparent materials, in particular, evaluation of damage-threshold fluence. General criterion for evaluation of damage threshold is deduced from the presented models are discussed.
