nLIGHT’s ytterbium fiber product series offers moderate to extremely high dopant concentrations resulting in application lengths suitable for multiple applications. Our direct nanoparticle deposition (DND) fiber production technology allows creating fibers with very high homogeneity minimizing clustering and photodarkening.
LIEKKI™ ytterbium fibers are available in the following fiber types
Single mode and large mode area (LMA)
Single, double and triple cladding
Polarization maintaining (PM) and non-PM
Our LIEKKI™ Yb700, Yb1200 and Yb2000 product series covers the broad application field of ytterbium fibers ranging from low-power preamplifiers to high-average-power pulsed amplifiers and high-continuous wave (CW) power fiber lasers.
