Smart Product Number: PLMA-GDF-15/130
15/130 Passive LMA Double Clad Fiber
Nufern's passive series of Large Mode Area (LMA) double clad fibers are ideal for high power monolithic fiber lasers and amplifiers. These passive fibers are based on a 15 µm diameter core and 130 µm diameter clad size with a low NA (0.08) core and are designed to work well with the active Yb-doped 15/130 LMA fibers. These fibers utilize the latest fiber design and NuCOAT coating technology to 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.
