Paper Abstract

We demonstrate a stable passive Q-switched fiber laser operating at 1560 nm. To realize pulsing generation, a piece of rose gold as a saturable absorber. The self-started Q-switching operation presence from 35 mW and stable until 142 mW pump power. By increasing the pump power to maximum level, generated pulse train has a maximum repetition rate of 89.89 kHz and short pulse width of 2.64 μs with a pulse energy of 103.08 nJ. The maximum output power is 8.56 mW. The obtained pulse is stable with a signal-to-noise ratio of 69 dB at 35 mW pump level.
