Coherent's PLMA-EYDF-25P/300-XPH fibers are optimized for high-power amplifiers operating in the 1.5 µm wavelength range. With a 25 µm core diameter and 300 µm cladding diameter, these fibers provide superior beam quality, high pump absorption, and excellent reliability under high power conditions. The XPH version ensures reduced 1 µm ASE and high conversion efficiency. NuCOAT fluoroacrylate™ coating guarantees durability and long-term performance in demanding industrial, medical, and defense applications.
