A new type of saturable absorber (SA) based on gold nanorods (GNRs) for all-fiber passively Q-switched erbium-doped fiber laser (EDFL) is realized experimentally. The longitudinal surface plasmon resonance (SPR) absorption of GNRs is used to induce Q-switching. By inserting the GNRs SA in an EDFL cavity pumped by a 980 nm laser diode, stable passive Q-switching is achieved with a threshold pump power of similar to 27 mW, and 4.8 mu s pulses at 1560 nm with a repetition rate of 39.9 kHz are obtained for a pump power of similar to 275 mW.
