We have fabricated tungsten disulfide (WS2) film and use this as saturable absorber (SA) in Erbium-doped fiber laser (EDFL) cavity to generate Q-switched pulses train. The SA was obtained by mixing WS2 into PVA solution to form a composite film after drying process. A stable Q-switched pulses train...
