Abstract
We report on the generation of a passively Q-switched erbium-doped fiber laser (EDFL) at 1567.6 nm, using aluminum nanoparticles (AlNPs) as a saturable absorber (SA). The synthesized film was fabricated by implanting AlNPs into polyvinyl alcohol as a host matrix. The SA thin film has a modulation depth of 7% and saturable intensity of 0.0015 MW cm−2. A small piece of composite film was inserted between two fiber ferrules to initiate Q-switching in the EDFL. Upon reaching a pump threshold of 156 mW, a stable Q-switching was achieved. As the pump power is steadily tuned from 156–300 mW, the repetition rate changes from 34.13–48.8 kHz, while the corresponding pulse duration varies from 3.4–2.17 µs. To the best of the authors’ knowledge, this the first demonstration of passive Q-switching employing an AlNP-based saturable absorber.
