The invention describes a method for the production of quartz glass which, in addition to a doping with rare earths and / or transition metals, comprises the fluorination of the quartz glass. The method described makes it possible to prevent outdiffusion of the dopants during the fluorination. Furthermore, the invention relates to the quartz glass obtainable by the process according to the invention and its use as a laser-active quartz glass, for the production of light-conducting structures and for use in optical applications. |
