Abstract
The use of tin disulfide (SnS 2) as a candidate material for saturable absorption in nonlinear optical devices is investigated in this article. A dual-wavelength soliton mode-locked fiber laser is demonstrated using a fabricated SnS 2 thin film as a saturable absorber within an erbium-doped fiber laser cavity. The laser generates two peaks centered at 1536.7 and 1562.6 nm, with a pulse width of 5.3 ps. The experimental results indicate that the SnS 2 thin film has the required absorption characteristics to realize good mode-locked operation. Thus, we confirm that SnS 2 has great potential to be used in multiwavelength ultrafast fiber laser applications.
