5/130 Ytterbium-Doped
Double-Clad Fiber
Nufern’s general purpose Ytterbium-Doped Double-Clad Fiber is available in two-versions — PANDA-style, polarizationmaintaining (PM) and non-PM. Designed specifically for CW applications around 1-15 W, these fibers are ideal for
applications requiring low-cost fiber laser and amplifier source, such as laser marking, fiber amplifier pumps and IR sources
for frequency doubling. These fibers’ telecom-type geometrics are compatible with readily available low-cost pump diodes
and fiber-based components.

Typical Applications

Features & Benefits

• Laser marking

• NuCOAT™ fluoroacrylate coating — Greater fiber durability in extreme environmental operating & storage conditions

• Fiber amplifier pumps

• Low cost double-clad technology — Enables use of high power multimode pump diodes

• IR sources for frequency doubling

• Single-mode output — Compatiable with standard telecom 980/1060 nm fiber-based components
• PANDA-style stress structure — Linearly polarized output for frequency conversion
