Novel heavy metal modified silica glass fibers doped with thulium, holmium, and thulium-sensitized-holmium high quantum efficiencies

摘要

A modified silica glass composition for providing a reduction in the multiphonon quenching for a rare-earth dopant comprising:SiO2 in a host material;a rare-earth dopant;a first SiO2 modifier; anda second SiO2 modifier; such that said first modifier and said second modifier reduce multiphonon quenching of the rare-earth dopant contained therein.
