The invention discloses a wavelength tunable ultrashort pulse fiber laser. The wavelength-tunable ultrashort pulse fiber laser comprises an ultrashort pulse fiber laser oscillator which comprises a semiconductor saturable absorber mirror, a first gain fiber and a chirp fiber bragg grating which are sequentially connected in series; the first semiconductor laser assembly is used for pumping the ultrashort pulse fiber laser oscillator; the ultrashort pulse fiber laser amplifier comprises a wavelength division multiplexer and a second gain fiber which are connected with each other; the second semiconductor laser assembly is used for pumping the ultrashort pulse fiber laser amplifier; and the energy controller is connected in series between the chirp fiber bragg grating and the wavelength division multiplexer and is used for adjusting chirp pulse energy output from the chirp fiber bragg grating to the ultra-short pulse fiber laser amplifier so as to realize adjustment of the laser center wavelength of the wavelen
