LIEKKI® Yb1200-20/400DC (HP, PM)(HELMI)

LIEKKI® Yb1200-20/400DC(HP, -PM) fibers are very highly doped fibers for high power fiber lasers and amplifiers. The fibers feature a large, low-NA core to provide excellent beam quality with large mode field diameter, very high pump absorption, low photodarkening loss and a 400 μm cladding capable of accepting high pump powers. Also available as a double-clad polarization maintaining fiber. LIEKKI® Yb1200-20/400DC (HP) is now also available with latest core design LIEKKI® HELMI* for increased photodarkening resistant.
