Ytterbium-Doped Single-Mode Single Clad Fiber - 1

Ytterbium-Doped Single-Mode Single Clad Fiber Nufern single-mode Yb-doped fibers are designed to support low power fiber lasers and amplifiers based on single-mode diode pump technology, rather than the multimode pumps used in high-power applications. For applications where high efficiency and very short device lengths are critical, these single-mode fibers are compatible with standard "telecom" fiber technology ensuring low splice loss to numerous fiber pigtailed components. The PM variety is designed with the PANDAstyle stress structure which delivers linearly polarized light suitable for frequency conversion. These fibers make the ideal gain medium for low average power femtosecond fiber lasers and pre-amplifiers for higher power double-clad amplifiers. Typical Applications Features & Benefits • Single-mode output — Compatiable with standard telecom 980/1060 nm fiber-based components fiber lasers • Femtosecond fiber lasers • Pre-amps for high-power, double-clad devices • PANDA-style stress structure — Linearly polarized output for frequency conversion • High Ytterbium concentration — Short fiber lengths to reduce detrimental non-linear effects • High slope efficiency (typically 75%) — Efficient utilization of pump power Optical Specifications Operating Wavelength Core NA Mode Field Diameter Cutoff Core Attenuation Core Absorption Birefringence 125.0 ± 1.0 µm 5.0 µm 245.0 ± 15.0 µm < 5.0 µm ≤ 0.50 µm UV Cured, Dual Acrylate -55 to 85 °C ≥ 100 kpsi (0.7 GN/m²) 125.0 ± 1.0 µm 5.0 µm 245.0 ± 15.0 µm < 5.0 µm ≤ 0.50 µm UV Cured, Dual Acrylate -55 to 85 °C ≥ 100 kpsi (0.7 GN/m²) 125.0 ± 1.0 µm 6.0 µm 245.0 ± 15.0 µm < 5.0 µm ≤ 0.50 µm UV Cured, Dual Acrylate -55 to 85 °C ≥ 100 kpsi (0.7 GN/m²) 125.0 ± 1.0 µm 6.0 µm 245.0 ± 15.0 µm < 5.0 µm ≤ 0.50 µm UV Cured, Dual Acrylate -55 to 85 °C ≥ 100 kpsi (0.7 GN/m²) Geometrical & Mechanical Specifications Cladding Diameter Core Diameter Coating Diameter Coating Concentricity Core/Clad Offset Coating Material Operating Temperature Range Prooftest Level The passive version of each fiber is also available.
