    The evolution between different types of pulses is the embodiment of the passive mode-locking fiber laser rich dynamics. A hybrid mode-locking fiber laser with multiple pulse switching was reported. When the pump power was 400 mW, the mutual switch of pulses between soliton molecules, harmonic mode-locking and soliton clusters were realized. Then, when the pump power was increased to 600 mW, the noise-like pulse output was realized, and the corresponding output power and single pulse energy were 15.2 mW and 0.86 nJ, respectively. By adjusting the polarization controller, the central wavelength of noise-like pulse could be tuned from 1 895 nm to 1 930 nm. The designed laser has the advantages of mode-locking switching, wavelength tuning and automatic start.
