Coherent Large Mode Area (LMA) matched passive double clad fibers are engineered for high-power laser systems. Featuring a 25 µm core diameter and a 400 µm cladding diameter, the M version ensures low splice loss and exceptional beam quality. The NuCOAT fluoroacrylate coating provides superior environmental durability, making these fibers an excellent choice for industrial, medical, and defense applications.
