Abstract: A quartz glass lamp vessel 1 or 21 is used in many types of lamps. Sometimes it is expedient to absorb a certain portion of the emission spectrum. In accordance with the prior art this is possible by including rare earth metal oxides in the quartz glass.
The solubility of rare earth metal oxides in quartz glass is, however, limited.
According to the invention, quartz glass is used which contains an alkali metal oxide and, optionally, an alkaline earth metal oxide, in addition to a rare earth metal oxide. The alkali metal oxide increases the solubility of the rare earth metal oxide, so that rare earth metal oxides can be used in larger concentrations. This results in glasses which have a higher degree of absorption, from which lamp vessels can be produced. Fig. 6 to be included.

Abstract: A doping optimized single-mode optical fiber with ultralow attenuation includes a core layer and cladding layers. The cladding layers has an inner cladding layer surrounding the core layer, a trench cladding layer surrounding the inner cladding layer, an auxiliary outer cladding layer surrounding the trench cladding layer, and an outer cladding layer surrounding the auxiliary outer cladding layer. The content of fluorine in the core layer is ≤ 0.5 wt%, Δ Ge ≤ 0.12%, Δn 1 ≤ 0.12%. The content of fluorine in the inner cladding layer is 0.5-1.5 wt%, Δn 2 ≤ -0.14%. The content of fluorine in the trench cladding layer is 1-3 wt%, Δn 3 ≤-0.25%. The content of fluorine in the auxiliary outer cladding layer is 0.5-2 wt%, Δn 4 ≤-0.14%. The outer cladding layer is a pure silicon dioxide glass layer and/or a metal-doped silicon dioxide glass layer. The present invention can decrease the viscosity of the core layer, so that the core layer can better match the inner cladding layer and the trench cladding layer. In addition, the core layer is combined with the metal-doped outer cladding layer having a matching viscosity. In this way, the virtual temperature of the optical fiber is overall decreased. And by means of the trench cladding layer design, fundamental mode leakage is restrained, thereby achieving ultralow attenuation performance.

Abstract: Ultralow expansion titania-silica glass. The glass has high hydroxyl content and optionally include one or more dopants. Representative optional dopants include boron, alkali elements, alkaline earth elements or metals such as Nb, Ta, Al, Mn, Sn Cu and Sn. The glass is prepared by a process that includes steam consolidation to increase the hydroxyl content. The high hydroxyl content or combination of dopant(s) and high hydroxyl content lowers the fictive temperature of the glass to provide a glass having a very low coefficient of thermal expansion (CTE), low fictive temperature (Tf), and low expansivity slope.
