5.5µm Diameter Operating at 1530-1625nm Erbium-Ytterbium Co-Doped Fiber

Erbium-ytterbium co-doped fiber is a single-mode active laser fiber. Its core is co-doped with erbium and ytterbium ions, its inner cladding is pure quartz, and its outer cladding is a low-refractive-index coating, forming a double-clad fiber structure. Fibercloud's erbium-mirror co-doped fiber offers high energy conversion efficiency, lowthreshold power, high output power, and excellent beam quality, making it suitable for fiber lasers and optical amplifiers. It meets the high-power output requirements of fiber lasers and amplifiers in long-distance optical communication networks, military, medical, and scientific research applications.
