| abstract |
This invention relates to glasses that are highly transparent and have very good resistance to solarisation. The good resistance to solarisation is favoured to a special extent by the production method. The concentrations of reduced polyvalent ion species are reduced by targeted use of bubbling with an oxidising gas. The invention also relates to a method for producing glasses according to the invention and to the uses thereof, particularly as core glasses in optical waveguides. In addition, this invention relates to an optical waveguide comprising the glass according to the invention as the core glass and a cladding glass. |
