Surface Versus Bulk Laser Damage Mechanisms

Moderators: Stavros Demos, Lawrence Livermore National Lab.(USA); Michael Feit, Lawrence Livermore National Lab. (USA)

The Round-Table discussion is a pre-symposium event that takes place during the registration on Sunday evening. The main purpose of the roundtable is to warm up symposium participants intellectually and to prepare them for active discussions during the Symposium. This year, the Round Table discusses the mechanisms of laser induced damage in the bulk and on the surface of optical materials. The discussion starts with a joint presentation by the moderators involving both up to date experimental results and theoretical interpretations. The focus is to identify similarities and differences in important physical properties and localized conditions occurring during a damage event induced on the surface versus in the bulk, and the corresponding material response after energy deposition leading to the formation of damage sites, i.e. irreversible observable modification. Although mostly excitation with nanosecond pulses will be considered in this discussion, some similarities and differences when using ultrashort pulses will be addressed.
