Abstract

The long-term performance of high-power laser systems is adversely affected by particle contaminants that are introduced into the system during the manufacturing of optical components and the handling during installation and operation of the laser system. Such particles can absorb or focus laser energy, reducing the laser-induced–damage threshold (LIDT) values. We developed ultrathin coatings that can decrease the overall load of contamination and aid with the removal of the already-accumulated particles using simple gas-flow cleaning. These coatings do not alter the intrinsic LIDT values, and they remain stable over time and during the system operation.
