Abstract

Janus transition metal disulfide (TMD) monolayers have two distinct carbon surfaces that break the inherent ground external mirror symmetry. When compared to traditional TMD materials, Janus TMDs not only inherit the advantages of traditional TMDs but also have new characteristics that are different from those of traditional TMDs. This paper describes the development of a stable passive Q-switched ytterbium-doped fiber laser (YDFL) with operating wavelengths of 1032.9 and 1030.6 nm using two saturated absorbing materials: tantalum sulfide (TaSSe) and tantalum disulfide (TaS₂). Our experimental results show that TaSSe, as a saturable absorber (SA), can generate a higher single-pulse energy and withstand higher pump power, and the single maximum pulse energy can reach 108.81 nJ. In the TaS₂-SA Q-switched YDFL, increasing pump power from 180 to 330 mW results in a minimum pulse width of 3.18 μs. The maximum pulse energy is 50.68 nJ. This study showed that Janus TMD TaSSe has superior optical properties compared to traditional TMD TaS₂, indicating that it has great potential for use in fiber laser development.
