In this paper, a 439 W, 1567 nm, narrow-linewidth Er/Yb co-doped fiber (EYDF) laser system pumped by 1018 nm fiber lasers is demonstrated. The 1018 nm fiber lasers are utilized as pumping source to suppress the ∼1 μm amplified spontaneous emission. It is the highest output power reported for EYDF lasers to date. A novel EYDF model considering the pair-induced quenching (PIQ) and the excited state ...Show More
