中文摘要: 中红外强场物理研究目前是强场激光物理领域一个非常重要的科学研究方向。本项目将利用中红外超强超短激光开展分子阈上电离和离解动力学的理论研究工作。在研究中我们分别采用合适的描述强激光场与分子相互作用的理论模型进行以下三个方面的研究: (1)分子结构和轨道的不对称性对分子阈上电离的影响; (2)各种物理效应对分子阈上电离的影响以及分子电离中新现象、新效应的探索; (3)利用周期量级中红外超强超短激光对分子的离解动力学进行控制。 本项目的目的是使人们能够深入地认识中红外超强超短激光场中分子复杂的电离和离解动力学行为,挖掘新物理、新效应和建立起依赖于激光波长的定律,并实现利用中红外新波段超强超短激光场控制分子离解动力学的目的。

英文摘要: The field of mid-infrared strong field physics at present is an very important investigated direction in the research of strong field laser physics. This project is supposed to theoretically investigate molecular above-threshold ionization and dissociation dynamics via strong, short-pulse mid-infrared laser fields. We will carry out our theoretical investigations by applying suitable theoretical models to the following three aspects accordingly: (1)Influence of molecular structure and orbital asymmetries on molecular above-threshold ionization; (2)Influence of various physical effects on molecular above-threshold ionization and exploration of new phenomena and effects; (3)Control of molecular dissociative dynamics by few-cycle strong, short-pulse mid-infrare laser fields. The aim of this project is to enable people further understand complex molecular ionization and dissociative dynamics in strong, short-pulses mid-infrared laser fields, to explore new effects in molecular ionization process and to establish the corresponding laws and relationships to laser wavelength, and to extend strong field control ability of molecular dissociative dynamics via strong, short-pulse mid-infrared laser fields.
