PLMA-GDF-10/400, PM Passive Double Clad Optical Fiber
Coherent's passive series of Large Mode Area (LMA) double clad fibers are ideal for high-power monolithic fiber lasers and amplifiers. These passive fibers feature a 10 µm core diameter and a 400 µm cladding diameter with a low NA (0.08) core. They are designed to work well with active Yb-doped 10/400 LMA fibers. Utilizing the latest fiber design and NuCOAT coating technology, these fibers ensure excellent preservation of beam quality and extended operating life at the high power levels demanded by today’s industrial fiber laser applications. These fibers are available in both non-PM and PANDA-style PM fibers.
Features
