摘要：
Q-switching pulses generation in an Erbium-doped fiber laser (EDFL) passively Q-switched by a silver nanoparticles (AgNP) based saturable absorber (SA) was experimentally demonstrated. The SA was fabricated by depositing nano-sized particles of Ag layer onto the surface of polyvinyl alcohol (PVA) film through the thermal evaporation process. By inserting the SA into an EDFL cavity, stable Q-switched operation was achieved at 1565 nm with the maximum pulse energy up to 34.7 nJ. The laser produced a range of pulse repetition frequency from 42.5 to 55.7 kHz with a minimal pulse width of 8.16 mu s. These results suggested that AgNP could be developed as an effective SA for Q-switching pulses generation.
