简介:

女,1996年在吉林大学原子与分子物理研究所获理学博士学位。1996-1998年在中国科学院物理研究所作博士后,出站后留所工作。2001-2003年在加拿大 University of Toronto 作博士后。现任中国科学院物理研究所研究员,博士生导师。

主要研究方向:

1。原子和分子与强激光场相互作用,包括强激光场中高次谐波产生(HHG)、电子的高阶阈值上电离(HATI)及双(多)电子非序列电离(NSDI、NSMI)过程。 2。阿秒脉冲的产生和应用。 3。利用强场重碰过程探测分子结构及操控分子在场中的动力学过程。 4。非重碰机制引起的强场效应及强激光场中的相对论效应。

过去的主要工作及获得的成果:

(1)发展非微扰量子电动力学理论,处理原子在强激光场中电子电离的重碰过程(re-collision processes);建立了强场全量子理论与半经典理论的对应关系;研究分子在强激光场中动力学过程,提出角度分辨的分子电离谱中量子相干条纹的产生机制,并预言在高频激光场条件下能够得到更清晰的分子结构成像;建立原子非序列电离过程的(non-sequential double ionization)频域理论。

(2)利用原子超精细计算方法,处理多电子原子和分子在强激光场中的动力学过程。考察原子激发过程中的激光脉冲载波相位效应(Carrier-envelope phase effect),证明相邻跃迁路径的量子相干是造成激发态CEP效应的原因。提出探测低频长脉冲激光载波相位方案。

(3)提出利用阿秒脉冲实现控制高次谐波产生的理论方案。发现利用超短脉冲产生的高次谐波谱可以探测电离电子波包的瞬间结构;并证明可以利用谐波谱直接探测里德堡态电子密度空间分布及波包动力学相干过程.
 
(4)利用静电场和双色场及原子高里德堡态提高谐波产生效率。

(5)利用外场调控超短强激光场中原子非序列电离过程,首次提出‘激光辅助碰撞电离’新机制,并解释实验上离子动量分布结果。
