  • Synthetic silica glass optical material having high resistance to optically induced index change
    Patent number: 7265070
    Abstract: Disclosed is a synthetic silica glass optical material having high resistance to optical damage by ultraviolet radiation in the ultraviolet wavelength range, particularly in the wavelength region of less than about 250 nm and particularly, exhibiting a low laser induced density change. The synthetic silica glass optical material of the present invention contains at least about 0.1 ppm of aluminum and H2 concentration levels greater than about 0.5×1017 molecules/cm2. Additionally, the synthetic silica optical material of the present invention exhibits an H2 to Al ratio of greater than about 1.2, as measured in ×1017/cm3 molecules H2 per ppm Al.

  • Method for producing bulk fused silica
    Patent number: 6378337
    Abstract: A method for preparing high-purity, bulk fused silica includes supplying silane gas, a gaseous fuel, and oxygen gas to a combustion burner. Silica particles are formed by passing the silane gas into a flame formed by the combustion reaction of the gaseous fuel with the oxygen gas while maintaining the ratio of the flow rate of the gaseous fuel to the flow rate of the silane gas no less than twelve and the ratio of the flow rate of the gaseous fuel to the flow rate of the oxygen gas no less than three. The silica particles formed are immediately deposited onto a hot bait to form a boule.
