    Abstract: A fused silica glass article having greater resistance to damage induced by exposure to laser radiation such as laser induced wavefront distortion at deep ultraviolet (DUV) wavelengths, and behaviors such as fluence dependent transmission, which are related to intrinsic defects in the glass. The improved resistance to laser damage may be achieved in some embodiments by loading the glass article with molecular hydrogen (H2) at temperatures of about 400° C. or less, or 350° C. or less. The combined OH and deuteroxyl (OD) concentration may be less than 10 ppm by weight. In other embodiments, the improved resistance may be achieved by providing the glass with 10 to 60 ppm deuteroxyl (OD) species by weight. In still other embodiments, improved resistance to such laser damage may be achieved by both loading the glass article with molecular hydrogen at temperatures of about 350° C. or less and providing the glass with less than 10 ppm combined OH and OD, or 10 to 60 ppm OD by weight.

    Abstract: A silica glass article, such as a lens in a stepper/scanner system, having saturated induced absorption at wavelengths of less than about 250 nm. Saturated induced absorption is achieved by first removing Si—O defects in the silica glass by forming silicon hydride (SiH) at such defects, and loading the silica glass with hydrogen to react with E′ centers formed by photolysis of SiH in the silica glass article. The silicon hydride is formed by loading the silica glass with molecular hydrogen at temperatures of at least 475° C. After formation of SiH, the silica glass is loaded with additional molecular hydrogen at temperatures of less than 475° C.
