Paper Abstract

An all-normal-dispersion WS2 mode-locked Yb-doped fiber laser was demonstrated. The saturable absorber (SA) is a piece of WS2-PVA film which is sandwiched between two fiber connectors. The modulation depth and saturation intensity of the WS2-PVA film were 1.78% and 81 MW/cm2 , respectively. When the WS2-PVA film was utilized in the laser cavity, stable mode locking occurred with the pump power of 140 mW. The maximum single pulse energy was estimated to be more than 2.82 nJ. Besides, in order to know more about the influence of the SA on the generation of ultrashort pulses, the dynamic evolution of mode-locked lasers with the parameters of SAs was studied by solving the Ginzburg-Landau equation. Thus the high pulse energy could be reached.
