LMA-YDF-20/400-VIII, Polarization-Maintaining Yb-Doped Double Clad Optical Fiber
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 20 µm core diameter and a 400 µm cladding diameter, the VIII version ensures high pump absorption and robust beam quality. The PANDA-style stress rods enhance birefringence, ensuring reliable polarization maintenance. The NuCOAT fluoroacrylate coating provides superior environmental durability and long-term reliability, making these fibers suitable for industrial, medical, and defense applications.
