Double-clad Yb-doped fibers

Double-clad Yb-doped fibers are engineered with a low numerical aperture and a large core diameter to minimize nonlinear effects, making them ideal for high-power, high-beam-quality laser output. These fibers boast excellent laser conversion efficiency and resistance to photodarkening, as well as outstanding reliability, consistency, and stability
