In this paper, two-dimensional Graphdiyne and Hexakis-[(trimethylsilyl)ethynyl]benzene nanosheets were prepared using the liquid-phase exfoliation method and were then successfully applied to 1.06 µm passively Q-Switched all-solid-state lasers. The Hexakis-[(trimethylsilyl)ethynyl]benzene was applied for the first time in passively Q-Switched all-solid-state lasers, as we know. For Graphdiyne, the Q-Switched pulse achieved a narrowest pulse width of 415 ns, a maximum repetition frequency of 244.2 kHz, a maximum pulse energy of 133.53 nJ, and peak power of 321.77 mW was obtained. While, the narrowest pulse width, maximum repetition frequency, maximum pulse energy, and peak power for Hexakis-[(trimethylsilyl)ethynyl]benzene are approximately 398.4 ns, 297.1 kHz, 89.61 nJ, and 220.39 mW respectively. The findings demonstrate the promising potential of both candidates as saturable absorbers for signal modulation in solid-state lasers.

以六-[(三甲基硅基)乙炔基]苯和石墨二炔作为可饱和吸收体的被动调Q Nd3+固体激光器

本文采用液相剥离法制备了二维石墨炔和六-[(三甲基硅基)乙炔基]苯纳米片，并成功应用于1.06 µm被动调Q全固态激光器。据我们所知，六-[(三甲基硅基)乙炔基]苯首次应用于被动调Q全固态激光器。对于Graphdiyne，调Q脉冲的最窄脉冲宽度为415 ns，最大重复频率为244.2 kHz，最大脉冲能量为133.53 nJ，峰值功率为321.77 mW。而六-[(三甲基硅基)乙炔基]苯的最窄脉冲宽度、最大重复频率、最大脉冲能量和峰值功率分别约为398.4 ns、297.1 kHz、89.61 nJ和220.39 mW。研究结果证明了这两种候选材料作为固态激光器信号调制的可饱和吸收体的巨大潜力。
