简介 |
The invention relates to a method for producing quartz glass which includes, in addition to doping with rare earth and/or transition metals, the fluorination of the quartz glass. As a result of the described method, the dopants can be prevented from diffusing out during the fluorination. Furthermore, the invention relates to the quartz glass obtainable by means of the method according to the invention and to the use thereof as laser-active quartz glass for producing light-guiding structures and for use in optical applications. |
