We are developing thermal- and laser-based processes for improving the resistance to laser-induced damage of multilayer dielectric coatings by understanding the underlying physics and chemistry responsible for the suppression of damage precursors. This research will result in a new class of multilayer dielectric coated optics that will enable advanced laser designs and operations tailored for national security missions.
