摘要： An optical member includes a fused silica glass having a concentration of ≡SiH moiety below detection limit as measured by Raman spectroscopy and a concentration of molecular hydrogen of at least 1×1017 molecules/cm3. The fused silica glass exhibits an induced absorption level which quickly attains an initial peak upon exposure to irradiation and rapidly decays to a low value. The induced absorption level after decaying to the low value remains substantially unchanged by further irradiation.

摘要： 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.

摘要： In furnaces for producing high purity fused silica glass boules, glass particles have a tendency to build-up adjacent the burner hole rim. It was discovered that unburned furnace gases containing silica particles where re-circulated in the furnace close to the burner hole rim and reacted with the oxygen of infiltrated air adjacent the burner hole, and thus deposited such particles in the form of a glassy build-up about the rim of the burner hole. In order to eliminate the source of oxygen adjacent the burner hole rim, a curtain of an inert gas is caused to flow through the burner hole between the sidewalls of the burner hole and the flame of the burner. Accordingly, the curtain of inert gas inhibits the combustion of the unburned hydrogen and carbon monoxide furnace gases adjacent the exit rim of the burner hole and thereby minimizes glass build-up about the burner hole rim.
摘要翻译：在用于生产高纯度熔融石英玻璃泡沫的炉中，玻璃颗粒具有在燃烧器孔边缘附近堆积的倾向。发现含有二氧化硅颗粒的未燃炉气体在炉内再循环到燃烧器孔边缘并与燃烧器孔附近的渗透空气的氧气反应，从而以玻璃状积聚的形式沉积这些颗粒关于燃烧器孔的边缘。为了消除燃烧器孔边缘附近的氧源，使惰性气体的窗帘流过燃烧器孔的侧壁和燃烧器的火焰之间的燃烧器孔。因此，惰性气体幕帘阻止燃烧器孔的出口边缘附近的未燃烧的氢气和一氧化碳炉气的燃烧，从而使关于燃烧器孔边缘的玻璃积聚最小化。
