PLMA-YDF-25/400-M, Matched Yb-Doped Double Clad Optical Fiber

Product image of PLMA-YDF-25/400-M, Matched Yb-Doped Double Clad Optical Fiber

Coherent Large Mode Area (LMA) matched Yb-doped fibers are optimized for high-power laser and amplifier systems. Featuring a 25 µm core diameter and a 400 µm cladding diameter, these fibers provide low splice loss and exceptional beam quality. The matched (M) design ensures seamless integration with active fibers. The NuCOAT fluoroacrylate coating enhances environmental durability, making these fibers suitable for industrial, medical, and defense applications under demanding conditions.
