Mode-locked fiber laser with tunable repetition and pulse width is widely used in optical communication and measurement applications.Usually the repetition and pulse width of the active mode-locked fiber laser can not be tuned independently.It is difficult to shorten the pulse width for a given repetition.In this experiment,we use multiple frequency modulation mode-locking(MFM-ML)method to drive mode-locker.The signal which is mixed by sine wave and rectangular wave is used as drive signal.By changing the parameter of the signal we obtain 4 different output pulse respectively,the pulse width are 705 ps,500 ps,407 ps,330 ps.
