1106 nm Q-switched Nd:GAGG laser using gold nanocages as saturable absorbers

  • 摘要: 成功制备了金纳米笼溶液并将其作为饱和吸收体,实现了中心波长为1106 nm的Nd:GAGG激光器的调Q运转。在输出镜透过率为3%的激光器中,在泵浦功率6.70 W下获得的最大平均输出功率为98 mW,此时对应的脉冲重复率为206 kHz,最短脉冲宽度为436 ns;在输出镜透过率为7%的激光器中,当泵浦功率为7.69 W时,得到的最大平均输出功率为121 mW,最短脉冲宽度为370 ns,对应的脉冲重复率为170 kHz。实验结果证明了金纳米笼在近红外波段激光器中用作饱和吸收体的巨大潜力。
