    摘要： 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 less than about 250 nm and particularly, exhibiting a low laser induced wavefront distortion; specifically a laser induced wavefront distortion, measured at 633 nm, of between about −1.0 and 1.0 nm/cm when subjected to 10 billion pulses of a laser operating at approximately 193 nm and at a fluence of approximately 70 μJ/cm2. The synthetic silica glass optical material of the present invention comprises OH concentration levels of less than about 600 ppm, preferably less than 200 ppm, and H2 concentration levels less than about 5.0×1017 molecules/cm3,and preferably less than about 2.0×1017 molecules/cm3.

    摘要： Disclosed are process and apparatus for making oxide soot particles where an atomizing burner is used as well as process for making densified silica-containing glass bodies by using soot particles having specific surface area of less than about 50 m2/g. Large glass bodies can be produced with less drying time and less binders by using such particles. The invention is particularly advantageous for the production of TiO2-doped silica glass.
