A stable, passively Q-switched Yb:CaGdAlO laser based on Mo:BiVO saturable absorber was demonstrated. Close observations of the structure and morphology of the nanoparticles by using transmission electron microscope, Raman spectrum and linear absorption were measured. The nonlinear transmission of Mo:BiVO was characterized by a 30 ps laser with a central wavelength of 1064 nm and a repetition rate of 10 Hz. The experimental maximum output power of the pulsed laser was 510 mW with a repetition rate of 87 kHz and pulse width of 3.18 μs, corresponding to a peak power of 1.84 W and a single pulse energy of 5.8 μJ. The experimental results indicate that Mo:BiVO-SA is a great candidate for passively Q-switched lasers in the near infrared region.
展示了一种基于Mo:BiVO饱和吸收体的稳定被动调Q Yb:CaGdAlO激光器。利用透射电子显微镜、拉曼光谱和线性吸收对纳米颗粒的结构和形貌进行了仔细观察。用中心波长为1064 nm、重复频率为10 Hz的30 ps激光对Mo:BiVO的非线性传输特性进行了表征。脉冲激光器的实验最大输出功率为510 mW，重复频率为87 kHz，脉冲宽度为3.18 μs，对应峰值功率为1.84 W，单脉冲能量为5.8 μJ。实验结果表明，Mo:BiVO饱和吸收体是近红外区域被动调Q激光器的极佳候选材料。
