In this work, we successfully fabricated a transmissive saturable absorber (SA) with TiCT MXene using the spin-coating method. By inserting the TiCT saturable absorber into the diode-pumped solid-state (DPSS) Nd:YAG laser, a stable passively Q-switched operation was obtained near 1.06 μm. At a pump power of 4.5 W, we obtained the shortest pulse duration of 163 ns with a repetition rate of 260 kHz. The corresponding single pulse energy and peak pulse power were 3.638 μJ and 22.3 W, respectively. The slope efficiency and the optical conversion efficiency of the laser were 21% and 25.5%, respectively. To the best of our knowledge, this is the first time that TiCT was used in the passively Q-switched solid-state lasers. This work demonstrates that TiCT can be a promising saturable absorber for solid-state laser pulse generation.
在这项工作中，我们使用旋涂法成功制备了一种含TiCT MXene的透射型可饱和吸收体（SA）。通过将TiCT可饱和吸收体插入二极管泵浦固态（DPSS）Nd:YAG激光器中，在1.06μm附近实现了稳定的被动调Q运转。在泵浦功率为4.5W时，我们获得了最短脉冲持续时间163ns，重复频率为260kHz。相应的单脉冲能量和峰值脉冲功率分别为3.638μJ和22.3W。该激光器的斜率效率和光转换效率分别为21%和25.5%。据我们所知，这是TiCT首次用于被动调Q固态激光器。这项工作表明，TiCT有望成为用于固态激光脉冲产生的可饱和吸收体。
