Part #:
LMA-EYDF-25/300

The first true Large Mode Area (LMA) Er:Yb fiber featuring a unique low NA (0.1) Er:Yb core design, achieved without

sacrificing high pump conversion efficiency and developed for applications where robustly single-mode output beam quality is critical. The high NA (0.46) 300μm cladding waveguide allows for efficient coupling of high pump powers, while the large core diameter (25μm) maintains a large-mode field diameter and short device length, thereby minimizing deleterious non-linear effects such as SBS and SRS. Both non-PM and PANDA-style PM fibers are available, as are a range of support fibers for component and pigtail development efforts. As with all Nufern standard LMA fibers, these fibers are proof tested to 100 kpsi, an industry requirement for long-term reliability when coiling for mode filtering.
