Q-switched fiber laser was demonstrated by using tungsten disulfide (WS2), which was deposited onto D-shaped fiber 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 side-polished fiber to for...
