A passively ${Q}$-switched erbium-doped fiber (EDF) laser based on antimonene saturable absorber is exclusively and systematically demonstrated. Few-layer antimonene nanosheets are prepared and a passively ${Q}$-switched EDF laser based on the saturable absorption feature of antimonene is implemented. The pulse repetition rate varies from 25.3 to 76.7 kHz when the pump power changes from 41 to 345 mW. The shortest pulse duration is 1.58 µs with pulse energy of 37.9 nJ. The experiment displays some new characteristics, which indicates that there is still much work to do before the mechanism of saturable absorption characteristics of antimonene is completely revealed.
首次系统地展示了一种基于锑烯可饱和吸收体的被动调Q掺铒光纤（EDF）激光器。制备了少层锑烯纳米片，并基于锑烯的可饱和吸收特性实现了被动调Q掺铒光纤激光器。当泵浦功率从41毫瓦变化到345毫瓦时，脉冲重复频率在25.3至76.7千赫兹之间变化。最短脉冲持续时间为1.58微秒，脉冲能量为37.9纳焦。该实验展现出一些新特性，这表明在锑烯可饱和吸收特性的机理被完全揭示之前，仍有许多工作要做。
