摘要
为了探索二维材料作为被动调Q激光器的可饱和吸收体的更多可能性,利用预研磨液相剥离法(LPE)制备出锑烯纳米片,并借助拉曼光谱、X射线衍射(XRD)、扫描电子显微镜(SEM)、原子力显微镜(AFM)、UV-Vis-NIR分光光度计对样品的物相组成、微观结构及吸收性能进行表征。将锑烯纳米片作为可饱和吸收体首次在1.3μm发射波长的Nd∶GYAP全固态激光器实现被动调Q,其最短脉冲宽度为589 ns,重复频率为424 kHz,峰值功率为1.14 W,平均输出功率为284 mW,最大单脉冲能量为669.43 nJ。实验证明了锑烯纳米片具有在近红外区域作为全固态调Q激光器的可饱和吸收体的潜力。
In order to explore the possibility of using two-dimensional materials as saturable absorbers(SA) of passively Q-switched lasers, antimonene nanosheets were successfully prepared by pre-grinding liquid-phase-exfoliation(LPE) method. The phase composition, microstructure and absorption properties of the samples were characterized by Raman spectrometer, X-ray diffraction(XRD), scanning electron microscope(SEM), atomic force microscope(AFM) and UV-Vis-NIR spectrophotometer. Based on the prepared synthesized antimonene nanosheets SA, an all-solid-state passively Q-switched Nd∶GYAP laser at 1.3 μm was realized for the first time. The shortest pulse width is 589 ns, the repetition rate is 424 kHz, the peak power is 1.14 W, the average output power is_(2)84 mW, and the maximum single pulse energy is 669.43 nJ. The results show that the antimonene nanosheets have the potential to become SA of all solid state Q-switched laser in the near infrared region.
