Description
Summary:In this letter, tin disulfide (SnS<sub>2</sub>) nanosheets were employed as saturable absorber for obtaining passively mode-locked Yb-doped fiber laser. A SnS<sub>2</sub>-PVA film was fabricated by incorporating the SnS<sub>2 </sub> nanosheets with the polyvinyl alcohol (PVA), Based on the SnS<sub>2</sub>-PVA film as saturable absorber, passively mode-locked Yb-doped fiber laser at a central wavelength of 1062.66 nm was achieved. The 3-dB bandwidth, pulse width, pulse repetition rate, and maximum average output power were 8.63 nm, 656 ps, 39.33 MHz, and 2.23 mW, respectively. The results exhibit that SnS<sub>2</sub> has excellent saturable absorption properties, which are equivalent to the reported two-dimensional transition metal dichalcogenides (WS<sub>2</sub>, MoS<sub>2</sub>) and will have wide potential applications in the field of ultrafast photonics.
