摘要 飞秒激光具有超短的脉冲宽度和超强的峰值功率,已经成为测量和操控原子分子超快动力学行为的重要工具.但是强激光场下,原子分子行为非常复杂,多个反应通道纠缠在一起.全微分符合测量技术能够提供特定反应通道精确的动力学数据,推动了强场原子分子物理研究的快速发展.本文结合北京大学新建的冷靶反冲离子动量谱仪,介绍全微分符合测量技术在强场原子分子物理实验研究中的重要应用以及在强场原子分子物理实验研究方面取得的一些重要进展. Femtosecond laser has become an important tool for measuring and controlling ultrafast dynamics of atoms and molecules because of its ultra-short pulse duration and ultra-high peak intensity. However, the behaviors are very complicated for atoms and molecules in intense laser fields. Many reaction channels are entangled together. Fully differential coincidence measurement technology can provide precise experimental data for a particular reaction channel and promote the rapid development of strong field atomic and molecular physics research. In this review article, based on the newly-built cold target recoil ion momentum spectrometer at Peking University, we will introduce the importance of coincidence measurement technology for studying the strong field atomic and molecular physics as well as the important progresses achieved in the experimental study of strong field atomic and molecular physics.
