The experimental study of ultrashort pulse Yb3+-doped fiber ring laser was reported.The Yb3+-doped fiber laser was pumped by two 976nm semiconductor lasers.Self-starting mode-locking of the fiber laser was demonstrated by employing the polarization additive pulse mode-locking.Wavelength tuning of the short pulse was carried out by changing the length of the Yb3+-doped fiber and the position of the polarization controllers.When the Yb3+-doped fiber length was 1.6m,the laser oscillate at 1053nm with 9.5mW maximum output power and 23.7MHz repetition frequency,corresponding to ～6nm spectrum width.The result shows:the wavelength-tunable fiber laser of ultrashort pulse is achieved by changing the length of the Yb3+-doped fiber and the position of the polarization controller.
