Description
Summary:In this letter, tin disulfide (SnS 2 ) nanosheets were employed as saturable absorber for obtaining passively mode-locked Yb-doped fiber laser. A SnS 2 -PVA film was fabricated by incorporating the SnS 2 nanosheets with the polyvinyl alcohol (PVA), Based on the SnS 2 -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 2 has excellent saturable absorption properties, which are equivalent to the reported two-dimensional transition metal dichalcogenides (WS 2 , MoS 2 ) and will have wide potential applications in the field of ultrafast photonics.
