摘要：
We investigate the conversion of mode locking of bright pulses, dark pulses and dark-bright pulses in an Erbium-doped fiber laser (EDFL) based on a Molybdenum disulfide (MoS2) films saturable absorber (SA) experimentally. When the pump power is 150 mW, by changing the polarization controller (PC) to change the polarization state in the laser cavity, we observed the bright pulse trains, the dark pulse trains and the dark-bright pulses trains in turn. All pulse interval are about 58 ns, and the repetition frequency of pulse is 1.7 MHz. The study provides a method for the conversion among bright pulses, dark pulses and dark-bright pulses.
