Paper Abstract

The damage morphology change condition of 1064nm reflector under multi-shot was investigated. Two typical kind of damage, scald and delaminate, were careful characterized in the damage growth process by SEM. The scald damage tends to become delaminate damage under some certain condition. Huge experiments supports that this morphology change condition has a close connection with scald initial fluence, subsequent fluence and shot number. The relationship among these factors is for the first time achieved to offer the “safety lines” for components.
