130-VIII Double-Clad Ytterbium-Doped Fiber
The Coherent/Nufern general-purpose double-clad ytterbium-doped fiber comes in two designs: Panda-type polarization-maintaining fiber and non-PM fiber. It is an ideal double-clad ytterbium-doped fiber designed for 1-15W low-power CW fiber laser and fiber amplifier applications, and can be used in fields such as laser marking, fiber amplifier pumping and frequency doubling of infrared light sources.
