Controlled wavelength pulses have widespread applications in the fields of telecommunications, biomedical research, metrology, and laser processing. A wide wavelength tunable all-normal-dispersion femtosecond ytterbium-doped fiber laser is designed based on nonlinear polarization rotation with an intracavity birefringence induced spectral filter. Taking advantage of the intracavity-birefringence induced spectral filtering effect, the center wavelength of the mode-locked femtosecond pulse can be continuously tuned from 1 015 nm to 1 075 nm by properly rotating wave plate and adjusting angle of birefringent filter. Over the tuning range, it delivers pulses of 4.52 ps duration at a repetition rate of 25.6 MHz and an output power of 85 mW.
