Paper Abstract

Increased laser durability is realized by F-SiO2 protected coatings on CaF2 with subsurface-damage-free surface finishing. Surface reflection loss is reduced by fluoride-based antireflection coatings. The F-SiO2 protective coating approach can be extended to the fluoride-based AR coatings on subsurface-damage-free CaF2 optics. In this contribution, a laser-induced damage test was performed on an F-SiO2 protected fluoride-based AR coating on a subsurface-damage-free (SSD-free) CaF2 window with an ArF laser. Similar laser damage resistance was realized on the protected AR coated optics with more than 9% transmission gain when compared to that of the F-SiO2 coated.
