Fluoride Glass Fibers

Active Fibers

RE doped single mode fibers

Thanks to their high RE solubility (up to 100 000 ppm) and low phonon energy, LVF fluoride fibers offer dozens of active transitions, enabling a broad range of application possibilities from visible to the midinfrared.

We have a large stock of various designs  of ZFG or IFG doped single mode fibers.

Doped with: Dy, Ho, Tm, Er, Pr, Sm, Nd, Yb…

Co-doped with: Er/Yb, Pr/Yb, Tm/Yb, Ho/Pr, Tm/Nd, Tm/Dy, Tm/Pr, Tm/Ho, Ce/Tm..
