Q-switched fiber laser was demonstrated by using tungsten disulfide (WS2) two-dimensional nanomaterials as a passive saturable absorber (SA) to modulate the loss inside the laser cavity. The SA was produced by repeatedly dropping and drying the WS2 solution onto microfiber to form a nanosheets layer...
