optical fiber for laser

For fiber lasers from 1.9 to 2.2 µm

iXblue carries a full range of Thulium and Holmium doped optical fibers for amplifiers and fiber lasers. iXblue’s Thulium doped fiber products have been developed for core pumped fiber lasers and amplifiers.

Our Single clad Holmium doped fiber can be pumped by a Thulium doped fiber laser with direct core pumping.
