Executive Summary

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.
