A high power 1018 nm continuous wave ytterbium-doped fiber laser was presented. The relationship of laser threshold power and gain fiber length in YDF was simulated and analyzed,and amplified spontaneous emission (ASE) is suppressed effectively by appropriately selecting length of YDF. The 1018 nm continuous wave laser output with a output of 300 W and a power conversion efficiency of 81% is obtained when the pumping power is 370 W
