    Abstract

    Wavelength switchable and tunable dissipative soliton mode-locking Yb-doped fiber laser based on nonlinear polarization rotation was studied. Due to the in-cavity comb filtering effect induced by NPR, the central wavelength of laser spectrum could switch between 1 042.8-1 050.2 nm, and 1 040.9-1 048.1 nm. The switchable wavelength intervals were 7.4 nm and 7.2 nm, respectively, and the spectral widths were about 5.5 nm and 2.7 nm. At the same time, the wavelength tunable operation was observed from 1 042.77 nm to 1 045.33 nm with the tuning range of 2.7 nm. In addition, stable dual wavelength mode locking and second harmonic mode locking were obtained in the fiber laser. The research of this experiment is helpful to deepen people's understanding of mode-locking dynamics in Yb-doped fiber laser and provide reference for the design of multi-function laser light source.
