A mode-locked(ML)picosecond ytterbium-doped thin disk laser using a monolayer Mo S2as the saturable absorber(SA)is demonstrated.The monolayer MoS_2 is fabricated through the method of low-pressure chemical vapor deposition.The laser directly produces stable ML picosecond pulses at a slope efficiency of 9.71%.The maximum output power is approximately 890 mW,while the corresponding repetition,pulse energy,and pulse duration are 48.6 MHz,18.3 nJ,and 13.1 ps,respectively.Results suggest that the monolayer MoS_2 is a promising SA for ultrafast lasers system.
