阿秒脉冲的特性对于超快现象的研究具有重要意义。本文提出了一种基于激光修饰XUV光电离的测量阿秒XUV脉冲的新方案。光电离的超短阿秒选通导致光电子谱中的干涉结构。这样就可以直接从光电子谱中以较高的分辨率反演阿秒XUV脉冲的持续时间。
The characterizing of attosecond pulses has great importance for the investigation of ultrafast phenomena. Here, we proposed a novel and efficient scheme for measuring attosecond XUV pulses, which is based on laser-dressed XUV photoionization. The ultrashort attosecond gating of photoionization leads to an interference structure in the photoelectron spectrum. Then the duration of the attosecond XUV pulse can be retrieved directly from the photoelectron spectrum with a rather high resolution.
