Abstract

A mode-locked (ML) picosecond ytterbium-doped thin disk laser using a monolayer MoS₂ as the saturable absorber (SA) is demonstrated. The monolayer MoS₂ 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 MoS₂ is a promising SA for ultrafast lasers system.
