Coherent Large Mode Area (LMA) polarization-maintaining Yb-doped fibers are designed for high-power laser and amplifier systems requiring linearly polarized output. With a 30 µm core diameter and a 250 µm cladding diameter, the VIII version ensures high pump absorption and excellent beam quality. PANDA-style stress rods enhance birefringence, ensuring reliable polarization maintenance. The NuCOAT fluoroacrylate coating ensures environmental durability and long-term reliability, making these fibers ideal for industrial, medical, and defense applications.
