Title: Mechanisms of Near-Ultraviolet, Nanosecond-Pulse--Laser Damage in Hf0 2/SIO 2--Based Multilayer Coatings

The possible role of metal clusters and electronic defects in the near-ultraviolet, nanosecond-pulse–laser damage in HfO 2/SiO 2-pair-based coatings is analyzed using experimental results on absorption and damage in HfO 2 monolayers with and without artificially introduced Hf nanoscale absorbers. These studies reveal a damage mechanism specific to HfO 2/SiO 2 pair combination comprised of a high-melting-point material (HfO 2), where absorption starts, and a lower-melting-point material (SiO 2), where absorption can be initiated upon reaching the critical temperature. Based on this analysis we discuss possible modifications to coating designs and desirable properties of high- and low-index materials that might lead to improve nanosecond, near-ultraviolet laser-damage performance.
