Product Description
Product Introduction
Ytterbium-erbium co-doped fiber is a kind of single-mode active laser fiber. The core fiber is co-doped with erbium ions and ytterbium ions. The inner cladding is pure quartz material, and the outer cladding is a low-refractive-index coating, forming a double-cladding fiber structure. Ytterbium-erbium co-doped fiber features a high energy conversion rate, low threshold power, large output power, and good beam quality. It can be applied in fiber lasers and amplifiers, meeting the high-power output demands of fiber lasers and amplifiers in long-distance communication networks, military, medical, and scientific research fields.
