LIEKKI™ Yb1200-4/125 – Single Mode Ytterbium Doped Fiber

 LIEKKI Yb1200-4/125 fibers are highly doped single mode ytterbium fibers for low-noise, low-nonlinearity preamplifiers and lasers. Their telcom-like geometry makes them compatible with low-cost pump diodes and standard single mode passive fibers. They make an excellent preamplifier in a fiber amplifier chain with double cladding fiber acting as power amplifier.
