A kind of doped pumped fiber laser with high output power and good beam quality was studied.When the pump power reached 30W, the maximum output power of the doped fiber laser was 6.1W and the wavelength was about 2μm, The slope efficiency reaches 55.6% and the threshold for laser generation is 2.2 W. When the output power is 3.3 W, the measured beam qualities M2X and M2Y are 1.26 and 1.32, respectively.
