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