RARE-EARTH DOPED GAIN FIBERS

摘要

Rare earth oxides doped multicomponent glass fibers for laser generation and amplification, including a core and a cladding, the core comprising at least 2 weight percent glass network modifier selected from BaO, CaO, MgO, ZnO, PbO, K2O, Na2O, Li2O, Y2O3, or combinations; wherein the mode of the core is guided with step index difference between the core and the cladding, a numerical aperture of the fiber is between 0.01 and 0.04; core diameter is from 25 to 120 micron, and a length of the gain fiber is shorter than 60 cm.
