XUV荧光探测$\mathrm{CO_2}$爆炸团簇动力学
$\mathrm{CO_2}$ exploding clusters dynamics probed by XUV fluorescence
摘要：
由强激光脉冲激发的团簇是温暖致密物质的独特来源，一直是深入实验研究的主题。这些研究中的大多数涉及原子团簇，而分子团簇的演化由强激光脉冲激发的探索较少。在这项工作中，我们跟踪的动力学$\mathrm{CO_2}$团簇触发的几个周期的1.45- $μ$ m的驱动脉冲通过检测的XUV荧光诱导延迟800 nm的点火脉冲。观察到不同离子种类的荧光动力学之间的显著差异。
英文摘要：
Clusters excited by intense laser pulses are a unique source of warm dense matter, that has been the subject of intensive experimental studies. The majority of those investigations concerns atomic clusters, whereas the evolution of molecular clusters excited by intense laser pulses is less explored. In this work we trace the dynamics of $\mathrm{CO_2}$ clusters triggered by a few-cycle 1.45-$μ$m driving pulse through the detection of XUV fluorescence induced by a delayed 800-nm ignition pulse. Striking differences among fluorescence dynamics from different ionic species are observed.
