MM-EYDF-10/125-XP Double-Clad Fiber
Coherent/Nufern’s MM-EYDF-10/125-XP erbium/ytterbium-codoped fiber uses proprietary rare-earth doping for high performance and reliability. Its double-clad design has a 10um core, 125um cladding and core NA 0.21. Optimization provides high pump-conversion efficiency and high-power operation without efficiency saturation caused by parasitic ASE in the 1um band. The large core permits shorter fibers in high-power amplifiers to reduce nonlinear effects. NuCOAT-FA coating provides excellent dry-heat and damp-heat performance, repeatable coating stripping and longer service life. Applications include eye-safe 1.5um-band lidar, high-power pulsed fiber lasers and fiber amplifiers.

Fiber lasers and fiber amplifiers at eye-safe (1.5um) wavelengths; lidar (LIDAR); high-power pulsed fiber lasers and fiber amplifiers; high-power 1550nm fiber amplifiers.
Key Features
Optimized XP design provides high efficiency and low parasitic 1um ASE. NuCOAT-FA, the latest generation of fluorinated-coating technology, improves fiber durability and reliability during operation and storage in extreme environments. A large core permits short fiber lengths in high-power pulsed amplifiers. Double-cladding design provides high-power capability and high pump-conversion efficiency. All fibers are proof-tested to ≥100kpsi, a key to long-term reliability when coiled.
