We are developing an understanding of the physics of layer interfaces by investigating their physical and chemical properties, especially pertaining to ultrathin coatings on multilayer dielectric mirrors found in high-power laser systems. The goal is to improve coatings to extend the lifetime and performance of high-average-power pulsed-laser systems for scientific applications and lasers for emerging, directed-energy systems.
