主要研究方向:
近年来,得益于高次谐波产生技术的快速发展和完善,极大地促进了阿秒激光脉冲的应用,使得在电子以及核的本征运动时间尺度内观察并描述其运动规律成为现实。众所周知,光诱导的超快激发态动力学,即电荷转移和能量传递机制,是原子、分子、光物理、光化学以及光致生物反应的核心问题之一。本课题组主要基于超快激光装置,结合高次谐波产生技术,从事阿秒激光脉冲与原子、分子、液体水、水溶液、常温液相分子等体系相互作用导致的超快激发态动力学实验研究。
具体研究方向包括:

5, 液体水的电子态结构以及激发态动力学;
过去的主要工作及获得的成果:
基于高次谐波产生技术,液体微束技术和磁瓶式高分辨光电子谱仪技术,分别发展并建立了:气相(原子、分子),液相(液体水,水溶液,常温液相分子)样品的时间分辨光电子能谱,电子-电子符合能谱实验方案,并取得了以下代表性成果:
