30 µm Triple Clad Ytterbium-Doped Polarization Maintaining Fiber

Nufern’s Yb-doped triple-clad fibers are specifically designed to match industry standard diode power delivery fibers. As with our highly successful double clad fiber series these fibers are available with either single-mode or Nufern’s robustly single-mode LMA core technology. These fibers incorporate PANDA-style stress elements for superior polarization maintaining properties. The triple clad fibers utilize an additional 0.23 NA inner glass cladding waveguide. This additional feature ensures splice-ability with beam or pump delivery fibers and high power connectorization. It additionally provides an all glass primary waveguide for highest long-term power level capacity.

Applications
  • PM fiber lasers and amplifier
  • Very high power PM fiber lasers & amplifiers
  • Lasers & amplifiers with classically spliced pumps
  • Connectorized lasers & amplifiers
Features & Benefits
  • LMA core technology — Robustly single-mode high output power with reduced non-linearities
  • 0.23 NA inner glass cladding — Compatibility to fiber coupled pumps, compatibility to standard connectors
  • PANDA-style PM — Superior performance
  • Proprietary low index coating — Captures otherwise spilled light in challenging designs
