We investigated theoretically and experimentally the feasibility of realizing high-power narrow-linewidth fiber lasers in <1100 nm wavelength range using only ytterbium ions gain. The structure of the laser is much simpler than Yb-Raman fiber lasers. In this laser, amplified spontaneous emission is suppressed by adjusting the amplifier parameters, which are determined by the theoretical calculation results. In addition, the system is built based on FBG-based master oscillator power amplifier configuration. Finally, a 1105 nm fiber laser, which delivers 1.5 kW output power withtheM2 being ~1.4 and a ~70 GHz linewidth, has been realized.
