250-M Double-Clad Ytterbium-Doped Fiber
The Coherent/Nufern matched series large mode area (LMA) double-clad fiber is an ideal fiber for all-fiber integrated fiber lasers and amplifiers. Active and passive fibers are precisely matched to ensure splice compatibility of the entire optical component chain, such as fiber Bragg gratings and fiber couplers.
