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.
