Abstract

Fundamental aspects of multishot laser damage are considered: thermal instability in an optical medium due to pulse-to-pulse accumulation of absorbing defects,mechanisms of laser induced defect generation. Effective methods of suppressing a defect formation to increase laser damage resistance are discussed and illustrated by experimental data for various type optical materials.

Keywords:
multishot and singleshot laser damage, thermal instability, absorbing inclusion, accumulation effect, photoionization, photochemical, thermochemical, mechanochemical processes, thermoelastic stresses, leser damage resistance of crystals, glasses and polymers, laser conditioning
