摘要
This paper reports on the first gain-switched fiber laser in the 2 μm region that uses an adjustable self-pulsing Er-doped QML fiber laser as a pumping source. By adjusting the output of the self-pulsing laser, a stable gain-switched pulse with a minimum duration of 366.2 ns and an adjustable repetition frequency of 37–73 kHz at 1959 nm is generated. The maximum output power achieved is 26.5 mW, with a pulse energy of 0.35 μJ and a slope efficiency relative to the pumping power of 4.6 %. Our study demonstrates the potential of an adjustable self-pulsing fiber laser as an effective pumping source for gain-switched fiber lasers.
