本文报道了利用反射式二硫化钼作为可饱和吸收体，实现了Nd∶YVO4激光器的调Q和调Q锁模输出。Nd∶YVO4激光系统采用了折叠腔结构。在吸收抽运功率为4.47 W时，得到了输出功率为87.2 mW的调Q脉冲输出。在吸收抽运功率为4.75 W时，得到了输出功率为95.3 mW的调Q锁模脉冲输出。输出超短脉冲的中心波长为 1064.39 nm。本文对实验结果及现象进行了分析和讨论，为下一步的实验作了准备工作。

The generation of both Q-switched and Q-switched mode-locking pulses from Nd∶YVO4 laser using reflective MoS2 saturable absorber is reported. The Nd∶YVO4 laser system is designed as a folded cavity. At the absorbed pump power of 4.47 W, Q-switched pulses with average output power of 87.2 mW are obtained. The Q-switched mode-locking operation with average output power of 95.3 mW is achieved at the absorbed pump power of 4.75 W. The wavelength of the ultrashort pulses is centered at 1064.39 nm. The experimental results are analyzed, and a good preparation is made for the next-step work.
