摘　　要：文章以一个实验者的角度,介绍了分子的飞秒强光电离的研究现状.文章从对比飞秒激光电离质谱与纳秒激光电离质谱开始,接着介绍分子在激光场作用下的可能电离机理,着重描述了几个处理分子场致电离的理论模型和实验验证,最后对飞秒激光导致的分子在激光脉冲作用后取向研究进行了简单介绍.This review is written from an experimentalist＇s point of view and introduces the current status of the ionization of molecules in an intense laser field. The paper begins by comparing femtosecond laser mass spectra and nanosecond laser mass spectra. It continues with a description of the possible ionization mechanisms of molecules in the laser field, then focuses on the interpretation of the theoretical models for dealing with the field ionization of molecules and comparison of theoretical calculations with experimental measurements. The final section discusses the postpulse alignment of molecules induced by an intense femtosecond laser field.
