摘要： The present disclosure 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 disclosure 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. Thus, a laser component with improved efficiency is obtained. The present disclosure also relates to a method for producing the laser component.
