iXblue releases new single and dual clad Ytterbium doped fibers

The new additions to iXblue specialty fibers portfolio include a highly doped single clad 6 µm core diameter Ytterbium doped fiber and a low NA double clad 20 µm core diameter Ytterbium doped fiber.

The IXF-YDF-6-125 single clad Yb fiber features a 6 µm core and 125 µm cladding diameters. The doping level has been increased by a factor of three versus existing fibers, reaching 75 dB/m core absorption at 915 nm. This fiber is ideal to minimize path length in femtosecond fiber lasers or pre-amplifiers. The fiber is available in Polarization Maintaining (PM) or non-PM versions.


The IXF-2CF-YB-O-20-130-NL dual clad Yb fiber features a 20 µm core and 130 µm cladding diameter. The fiber features a 0.08 numerical aperture and was specifically developed for integration into high power industrial amplifiers and high peak power laser applications requiring good beam quality. The material composition of the fiber was carefully selected to avoid photodarkening effect.


Fiber Samples are available from stock upon request.

These two fiber releases reinforce iXblue’s position as a key and independent components provider for 1 µm fiber laser manufacturers. iXblue Photonics offers Specialty fibers, bragg gratings and Lithium Niobate electro-optic modulators.
