In this work, Q-switched fiber laser has been demonstrated in a bismuth-doped fiber laser (BDFL) system using tungsten ditelluride (WTe2) and tungsten disulfide (WS2) as saturable absorbers (SAs). The solution casting method was used to prepare both WTe2 and WS2 thin films SAs. At the threshold pump...
