MXene materials have shown numerous useful mechanical and electronic properties, and have been found to possess nice potential in the field of optical modulation. Here, we fabricated a MXene CrC saturable absorber by the liquid-phase exfoliation method, and systemically analyzed the surface morphology and nonlinear properties of the CrC sample. Applying the CrC saturable absorber as a Q-switch in a thulium-doped yttrium aluminum perovskite (Tm: YAP) laser, the shortest single pulse was obtained with a width of 602 ns under an absorbed pump power of 3.3 W at a repetition rate of 55 kHz with a T = 1% output coupler. The maximum output power was obtained with a T = 5% output coupler at a repetition rate of 58 kHz. The obtained maximum pulse energy and peak power were 3.96 μJ and 4.36 W, separately, which reveal that the MXene CrC can be applied as a promising modulation material in the near-infrared pulsed lasers.
MXene材料已展现出众多有用的机械和电子特性，并且发现在光调制领域具有良好潜力。在此，我们通过液相剥离法制备了一种MXene CrC可饱和吸收体，并系统分析了CrC样品的表面形貌和非线性特性。将CrC可饱和吸收体用作掺铥钇铝钙钛矿（Tm:YAP）激光器中的调Q开关，在重复频率为55 kHz、吸收泵浦功率为3.3 W、输出耦合器透过率T = 1%的条件下，获得了宽度为602 ns的最短单脉冲。在重复频率为58 kHz、输出耦合器透过率T = 5%的条件下获得了最大输出功率。所获得的最大脉冲能量和峰值功率分别为3.96 μJ和4.36 W，这表明MXene CrC可作为一种有前景的调制材料应用于近红外脉冲激光器。
