    Abstract: In a method for producing a quartz glass member, an F2 laser is radiated onto a sample obtained from a quartz glass base material under a predetermined condition to judge whether or not a peak intensity of H2 Raman scattering light is decreased by not less than 80% as compared with a peak intensity of H2 Raman scattering light obtained for a sample not irradiated with the F2 laser. If the peak intensity of H2 Raman scattering light is decreased by less than 80%, then it is judged that the laser resistance of the quartz glass base material is sufficient, and the synthetic quartz glass member is processed from the base material. The compaction of the sample is also measured.

    Abstract: The present invention provides an optical fiber providing high photosensitivity in the absence of hydrogen loading as well as a low numerical aperture. One aspect of the present invention relates to an optical fiber including a core, the core comprising silica doped with at least about 6 mol % germania and at least about 0.9 wt % fluorine; and a cladding surrounding the core. The optical fiber of the present invention is suitable for the production of fiber Bragg gratings.

    Abstract: High purity silicon oxyfluoride glass suitable for use as a photomask substrates for photolithography applications in the VUV wavelength region below 190 nm is disclosed. The inventive silicon oxyfluoride glass is transmissive at wavelengths around 157 nm, making it particularly useful as a photomask substrate at the 157 nm wavelength region. The inventive photomask substrate is a “dry,” silicon oxyfluoride glass which exhibits very high transmittance in the vacuum ultraviolet (VUV) wavelength region while maintaining the excellent thermal and physical properties generally associated with high purity fused silica. In addition to containing fluorine and having little or no OH content, the inventive silicon oxyfluoride glass suitable for use as a photomask substrate at 157 nm is also characterized by having less than 1×1017 molecules/cm3 of molecular hydrogen and low chlorine levels.
