摘要: A tellurite glass composition doped with a first lanthanide, preferably Tm, and codoped another lanthanide oxide, e.g. Ho, is provided. The includes 4-12 mole % of alkalihalide XY, X being selected from the group Li, Na, K, Rb, Cs Fr Y F, Cl, Br I. preferred contains about 10 CsCl. addition XY results in an enhanced energy transfer to second ion, whereby lower level ion depopulated. ratio between upper lifetimes for can be reduced value below one, enabling efficient amplifier fibers.
