【摘要】：强激光与原子分子相互作用时,有许多由电子关联效应导致的新现象.强激光场驱动下的原子分子双电离,特别是非次序双电离,是一种典型的由电子关联作用引起的物理过程,为人们研究电子关联效应提供了一种重要途径.本文介绍了基于冷靶反冲离子动量成像谱仪技术对强场双电离关联电子微观动力学的研究现状,总结了不同激光强度下非次序双电离的微观动力学过程,进一步介绍了基于双色场对非次序双电离关联电子动力学过程控制的理论及实验研究.最近强场次序双电离实验观察到了许多与以前的理论模型预言相悖的物理现象,本文介绍了最近发展起来的次序双电离模型对这些现象的解释,以及此理论模型预言的次序双电离的有趣现象.
[Abstract]:There are many new phenomena caused by electron correlation effect when strong laser interacting with atoms and molecules. Double ionization of atoms and molecules driven by intense laser fields, especially non-ordered double ionization, is a typical physical process caused by electron correlation, which provides an important way for people to study electron correlation effect. In this paper, the research status of electron microdynamics based on cold target recoil ion momentum imaging spectrometer for strong field double ionization correlation is introduced, and the microdynamic processes of irregular double ionization under different laser intensities are summarized. Furthermore, the theoretical and experimental study on the control of the electron dynamic process of disordered double ionization correlation based on the two-color field is presented. Recently, many physical phenomena contrary to the predictions of previous theoretical models have been observed in the strong field order double ionization experiment. The explanation of these phenomena by the recently developed order double ionization model is introduced in this paper. And the order of double ionization predicted by this theoretical model is interesting.
