Smart Product Number: PM-YSF-HI-HP
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 singlemode 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 PANDA-style 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. These High Performance (-HP) versions provide tighter optical and geometric tolerances, improving device performacnes, system compatibility and manufacturing process control.
