Where to Buy Rare-earth-doped Fibers

Thanks to their high rare-earth solubility (up to 100,000 ppm) and low phonon energy, LVF fluoride fibers offer dozens of active transitions, enabling a broad range of applications from visible to the mid-infrared. LVF offers the largest range of rare-earth doped fibers in the world.

LVF active fibers are available as rare-earth-doped single-mode fibers and rare-earth-doped double cladding fibers.

iXblue offers a wide range of specialty optical fibers for lasers and amplifiers. We master erbium, erbium/ytterbium, ytterbium, thulium, holmium, thulium/holmium, neodymium, dysprosium, and phosphorous gain media. PM version are available, and Large Mode Area (LMA) or Very Large Mode Area (VLMA) versions as well. Depending of the requirement, single clad fibers are available for core pumping, double clad fibers for clad pumping. Triple clad and all glass structures are also available.

Our ytterbium and thulium double clad fibers offer the largest single-mode cores in the world. They enable amplification to unprecedented power levels while keeping mode quality and stability. If you are building picosecond or femtosecond ultrafast fiber lasers, our Yb-doped aeroGAIN gain modules may be just what you are looking for.

FastFBR is INO’s line of Yb-doped PM fiber based on our low-photodarkening core chemistry. FastFBR has a fiber for every amplification stage of your high-power pulsed laser system: from the 5 µm core single-clad Yb401-PM, to our Yb-10/125-PM and Yb-15/125-PM fibers suitable for medium power amplification stage, and up to our Yb-35/250-PM and tapered PM fiber suitable for high-power amplification duties. This line of optical fiber is intended for industrial pulsed laser applications for which long-term reliability and output mode quality are of paramount importance.
