Abstract
A model of steady-state rate equations including amplified spontaneous emission for long-wavelength ytterbium-doped fiber laser is set up, which provides design principle for a practical laser system. We demonstrate a diode-pumped all-fiber Yb-doped fiber laser at 1150 nm with an output power of 33.6 W, the optical efficiency is 60%.
