LMA-GDF-20/130-M, Matched 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 are based on a 20 µm diameter core and a 130 µm diameter cladding with a low NA (0.08) core. They are designed to work well with active Yb-doped 20/130 LMA fibers. These fibers utilize the latest fiber design and NuCOAT coating technology to ensure excellent preservation of beam quality and extended operational 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.
