This paper demonstrates an all-fiber high-power Yb-doped 1064 nm fiber laser based on master oscillator power amplifier structure. The record output power up to 2625 W was achieved, along with a slope efficiency of 76%. The beam quality factor is Mx2＝1.273, My2＝1.255, and full width at half maximum is 21.7 GHz at maximum power level. The fiber laser has the highest output power of all-fiber lasers with 22 GHz linewidth.
