We studied the dynamics of solvated electrons in the early stage of plasma generation in water induced with an intense femtosecond laser pulse. According to the decay kinetics of solvated electrons, a fast recombination process of solvated electrons (geminate recombination) occurred with a more prolonged lifetime (500 ps to 1 ns) than that observed in previous pulse photolysis studies (10–100 ps). This unusually longer lifetime is attributed to additional production of solvated electrons due to abundant free electrons generated with the laser-induced plasma, implying significant influence of free electrons on the dynamics of solvated electrons.

飞秒激光诱导水中等离子体生成过程中溶剂化电子的动力学

我们研究了在强飞秒激光脉冲诱导的水中等离子产生的早期阶段中溶剂化电子的动力学。根据溶剂化电子的衰变动力学，与以前的脉冲光解研究（10-100 ps）相比，溶剂化电子的快速重组过程（geate重组）的寿命更长（500 ps至1 ns）。这种异常长的寿命归因于由于激光诱导的等离子体产生的大量自由电子，导致溶剂化电子的额外产生，这意味着自由电子对溶剂化电子的动力学有重大影响。
