We have fabricated gold nanoparticles (GNP) based saturable absorber and used it to passively Q-switch an Erbium-doped fiber laser (EDFL). By adjusting a tunable filter, the laser operation is tunable from 1535 to 1560 nm. The highest slope efficiency of 23.38% is obtained at 1545 nm. At this operat...
