LIEKKI® Yb1200-20/400

LIEKKI® Yb1200-20/400 fibers are very highly doped fibers for high power fiber lasers and amplifiers. The fibers feature a large, low-NA core with excellent beam quality, very high pump absorption, low photodarkening loss  and a 400 μm cladding capable of accepting high pump powers.
LIEKKI® Yb1200-20/400 fibers are available as double-clad (Yb1200-20/400DC) and double-clad polarization maintaining (Yb1200-20/400DC-PM) fibers.
