Optical fiber for a high performance - fiber laser, its production as well as high performance - fiber laser, comprising the optical fiber

摘要

Optical fiber for use as a laser medium in a fiber laser, in particular high performance - fiber laser, comprisinga core, doped with laser active material, in particular rarely - erdatomen,a casing which surrounds the core,with the casing has a microstructuring andthe material for the fiber core and / or fiber shell made of glass ceramic, on the basis of the glasses lithium - and - containing aluminum silicate glasses, heavy metal oxide glasses, silica glasses, phosphate, phases separated-out glasses, glasses with domains.
