High-power narrow-linewidth tunable Er3+/Yb3+ co-doped cladding-pumped fiber ring laser

摘要

A tunable Er3+/Yb3+ co-doped cladding-pumped all fiber ring laser is presented. Under the maximum pump power of 3594.5mW, the absorbed pump power of the fiber is measured to be 2737.37mW, the maximum output power of the fiber laser is 438mW, and the slope
