5/130 Ytterbium-Doped Double-Clad Fiber - 1

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 Optical Specifications Operating Wavelength Core NA First Cladding NA (5%) Mode Field Diameter Cutoff Core Attenuation Cladding Attenuation Cladding Absorption Birefringence 1060 – 1115 nm 0.120 ≥ 0.46 6.5 ± 0.5 µm @ 1060 nm 950 ± 50 nm ≤ 15.0 dB/km @ 1200 nm ≤ 15.0 dB/km @ 1095 nm 0.60 ± 0.10 dB/m at 915 nm 1.80 dB/m near 975 nm 2.5 × 10⁻⁴ 1060 – 1115 nm 0.120 ≥ 0.46 6.5 ± 0.5 µm @ 1060 nm 950 ± 50 nm ≤ 10.0 dB/km @ 1200 nm ≤ 15.0 dB/km @ 1095 nm 0.55 ± 0.10 dB/m at 915 nm 1.65 dB/m near 975 nm N/A Geometrical & Mechanical Specifications Cladding Diameter Cladding Diameter (flat-to-flat) Core Diameter Coating Diameter Coating Concentricity Core/Clad Offset Prooftest Level The passive version of each fiber is also available - see PM-GDF-5/130 and SM-GDF-5/130 7 Airport Park Road, East Granby, CT 06026 • 860.408.5000 • Toll-free 866.466.0214 • Fax 860.844.0210 E-mail info @ nufern.com • www.nufern.com • Nufern products are manufactured under an ISO 9001:2008 certified quality management system.
