三元硫系化合物具有良好的上级非线性光学响应，在未来的光子器件中具有广阔的前景。采用液相剥离法制备了Ta2NiS5和Ta2NiSe5纳米片。以Tm：YAG陶瓷和Tm，Ho：Ca（Gd，Lu）AlO4晶体为增益介质，实现了Ta2NiS5和Ta2NiSe5可饱和吸收体的双被动调Q激光器。在Tm，Ho：Ca（Gd，Lu）AlO4激光器中实现了最短脉宽391 ns的激光输出。在Tm：YAG陶瓷激光器中获得了最高峰值功率17.73W。结果表明，Ta2NiS5和Ta2NiSe5纳米材料具有产生短脉冲激光的潜力。双调Q技术可以压缩脉冲宽度，提高峰值功率。
Ternary chalcogenides possess a promising prospect for their superior nonlinear optical response, offering new opportunities in future photonic devices. Ta2NiS5and Ta2NiSe5nanoflakes fabricated by liquid-phase exfoliation were investigated. Based on Tm:YAG ceramic and Tm,Ho:Ca(Gd,Lu)AlO4crystal as gain media, the doubly passively Q-switched lasers with Ta2NiS5and Ta2NiSe5saturable absorbers were realized. The shortest pulse duration was 391 ns, which was realized in Tm,Ho:Ca(Gd,Lu)AlO4laser. And the highest peak power 17.73 W was obtained in Tm:YAG ceramic laser. The results demonstrate that the Ta2NiS5and Ta2NiSe5nanomaterials have the potential to generate a short-pulsed laser. Doubly Q-switching technology can compress pulse duration and enhance peak power.
