LMA-TDF-25P/250-LC, Large Mode Area Tm-Doped Fiber
Coherent Large Mode Area (LMA) Tm-doped fibers are designed for laser and amplifier systems operating at ~2 µm. With a 25 µm core diameter and a 250 µm cladding diameter, the LC version is optimized for low cladding absorption and extended operational life. The NuCOAT fluoroacrylate coating enhances environmental durability, making these fibers suitable for industrial, medical, and defense applications requiring consistent performance under challenging conditions.
