LIEKKI® Yb1200-25/250DC (-PM)(HELMI)

Feb 3

LIEKKI® Yb1200-25/250DC(-PM) fibers are very highly doped fibers which feature very high cladding absorption at low photodarkening loss, high efficiency per application length and excellent beam quality. These fibers are ideal for high power pulsed fiber amplifiers where short application lengths are crucial to avoid nonlinear effects. LIEKKI® Yb1200-25/250DC is now also available with latest core design LIEKKI® HELMI* for increased photodarkening resistant.
