Ho Doped Fibers

Lasers & Amplifiers Fibers

# #


For fiber lasers from 1.9 to 2.2 µm

iXblue carries a full range of Holmium doped optical fibers for amplifiers and fiber lasers. Our single clad Holmium doped fiber can be pumped by a Thulium doped fiber laser with direct core pumping.

For high power CW and pulsed lasers ~2 µm

Triple clad design to be used in high power regime for amplifiers and fiber lasers configuration.
