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..
