Nanosecond single- and multiple-pulse laser damage studies on HfOffSiO2 high-reflection (HR) coatings are performed at 532 nm. For single-pulse irradiation, the damage is attributed to the defects and the electric i...
The possible role of metal clusters and electronic defects in the near-ultraviolet, nanosecond-pulse-laser damage in HfO2/SiO2-pair - based coatings is analyzed using experimental results on absorption and damage in H...
Single-pulse and multi-pulse damage behaviors of "standard" (with A/4 stack structure) and "modified" (with reduced standing-wave field) HfO2/SiO2 mirror coatings are investigated using a commercial 50-fs, 800...
