10/130 Ytterbium-Doped LMA Double Clad Fiber Featuring the latest Gen VIII glass composition, Nufern’s large mode area (LMA) and PM-LMA Ytterbium-doped double clad fibers are ideally suited for applications spanning military, industrial and medical including linearly polarized fiber lasers and amplifiers. LMA Yb-doped fibers enable efficient, compact, diode pumped fiber sources that are an attractive alternative to traditional solid-state lasers. This fiber features a single mode large core/cladding ratio with a low NA and is ideally suited for both CW and pulsed laser applications. Typical Applications Features & Benefits • Pulsed fiber lasers and amplifiers • NuCOAT™ fluoroacrylate coating — Greater fiber durability in extreme environmental • Material processing operating & storage conditions • LMA core design and short amplifier length — Useful for generating high peak powers • LIDAR • Non-linear optics / frequency doubling • Easy to maintain single mode LP01 beam through fiber & components • PANDA-style stress structure for increased birefringence — Superior optical performance and uniformity • All fiber proof tested to > 100 kpsi — Critical for ensuring long term reliability when coiling Optical Specifications Operating Wavelength Core NA First Cladding NA (5%) Cladding Attenuation Cladding Absorption Birefringence PLMA-YDF-10/125-VIII LMA-YDF-10/130-VIII 1060 – 1115 nm 0.075 ≥ 0.460 ≤ 15.0 dB/km @ 1095 nm 1.60 ± 0.20 dB/m at 915 nm 4.80 dB/m near 976 nm nominal 3 × 10⁻⁴ 1060 – 1115 nm 0.075 ≥ 0.46 ≤ 15.0 dB/km @ 1095 nm 1.30 ± 0.20 dB/m at 915 nm 3.90 dB/m near 975 nm N/A 125.0 ± 2.0 µm N/A 11.0 ± 1.0 µm 245.0 ± 15.0 µm ≤ 1.00 µm Low Index Polymer ≥ 100 kpsi (0.7 GN/m²) N/A 130.0 ± 3.0 µm 11.0 ± 1.0 µm 245.0 ± 15.0 µm ≤ 1.00 µm Low Index Polymer ≥ 100 kpsi (0.7 GN/m²) Geometrical & Mechanical Specifications Cladding Diameter Cladding Diameter (flat-to-flat) Core Diameter Coating Diameter Core/Clad Offset Coating Material Prooftest Level The precision matched fiber sets are also available - see PLMA-YDF-10/125-M; LMA YDF-10/130-M; PLMA-GDF-10/125-M and LMA-GDF-10/130-M 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.
