Abstract

A study of free electron laser (FEL) related optical damage is currently under way at Los Alamos National Laboratory. A single burst of the FEL has been simulated using a Nd:YAG laser system operating at 1064 nm. Thfe laser is a modelocked, 100 microsecond, pulse selected system operating at 10 pulses per second.

Damage thresholds for conventionally deposited dielectric high reflectors as well as bare metals have been studied and the results are reported. Some high reflectors have demonstrated laser induced damage thresholds of greater than 5 megawatts/cm² average pulse power.

Also, reported are damage data for a non-modelocked laser configuration.
