摘要： Glasses are provided that are highly transparent and have very good resistance to solarisation. The 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. Methods for producing glasses and to the uses thereof, particularly as core glasses in optical waveguides, are also provided.

摘要： The glasses of the present disclosure are highly transparent and have very good resistance to solarization. The resistance to solarization arises from the production method. The concentrations of reduced polyvalent ion species are reduced by targeted use of bubbling with an oxidizing gas. Methods for producing glasses and to the uses thereof, particularly as core glasses in optical waveguides, are also provided.

摘要： The present invention relates to optical glasses, in particular special short flint glasses (KZFS) and optical elements and components, which comprise these glasses, and use thereof and a method for producing such optical glasses. The optical glasses of the present invention are characterized by a pronounced short flint character and additionally by an excellent transmission and chemical resistance and workability. At that, the glasses of the invention can stand out due to lower costs of production caused by lower costs of raw materials and lower processing costs, due to their crystallization properties that can be handled also in smaller melting aggregates, and due to good environmental compatibility.

摘要： The present invention relates to a glass having a refractive index of at least 1.7 as well as the use of the glass as a cladding glass of a solid-state laser. The invention also relates to a laser component comprising a core of doped sapphire and a cladding glass being placed on said core. The cladding glass is arranged on said core such that light exiting from the core due to parasitic laser activity can enter the cladding glass and can be absorbed there. The present invention also relates to a method for producing the laser component.
