The Yb-doped fiber ring laser using LD pumping source is reported. The laser system consists of 3 m length fiber and 1053 nm/980 nm WDM which form a crossing all-fiber ring. The length of the cavity is 4 m, pump wavelength 980 nm.The output wavelength 1042.3 nm, slope efficiency 9.6% and threshold smaller than 0.5 mW were obtain. The tunable Ti:shapphire laser is also used as pump source and the optimal pump wavelength 978 nm was observed.
