Abstract: Optical wave guides made of quartz glass with reduced infrared absorption and reduced attenuation coefficients are made of a glass which consists of atoms with a mass-number higher than that of the natural isotope ratio. The quartz glass or doped quartz glass consists of silicon atoms of which most or all have the mass-numbers 29 and/or 30, as well as oxygen atoms of which most or all consist of isotopes with the mass-numbers 17 and/or 18. For doping with germanium atoms with higher mass-numbers than in the natural isotope mixture, atoms of the Ge isotope are preferably used. For optical wave guides based on quartz glass with attenuation coefficients below 0.15 dB/km, glass with atoms of preferably Si and/or O are preferably used. Such optical wave guides are also suitable for transmitting high-energy, pulsed or continuous laser light in a wavelength range from 2.0 to 3.0 mu m. These optical wave guides are also suitable for transmitting holmium laser light of 2.1 mu m and er laser light with a wavelength equal to 2.79 and 2.94 mu m.

Abstract: The present invention is directed to a method for making silica. A liquid siloxane-containing feedstock capable of being converted by thermal oxidative decomposition to SiO2 is provied and introduced directly into the flame of a combustion burner, which converts the compound to silica, thereby forming finely divided amorphous soot. The soot is vaporized at the conversion and/or deposition site where the liquid is converted into silica by atomizing the liquid with a stream of oxygen gas, or a mixture of oxygen gas and other gas, such as nitrogen. The amorphous soot is deposited on a receptor surface where, either substantially simultaneously with or subsequently to its deposition, the soot is consolidated into a body of fused silica glass, such as an optical fiber preform.
