This tutorial provides an overview on the theory of attosecond streaking, a pump-probe scheme to extract timing information of ionization processes that has been widely used in the past decade. Emphasis is put on the origin of the Coulomb-laser-coupling (CLC) term, which is crucial in the interpretation of streaking delays. Having gained a proper understanding of how the CLC terms in various publications relate to each other, we will be able to analyze in which regime the streaking delay can be split into a measurement-induced CLC term and a ‘pure’ ionization delay and under which conditions this splitting may break down. Thus we address the long-standing question of the validity of the widely applied interpretation of the streaking delay as a sum of the CLC term and a ‘pure’ ionization delay.

了解阿秒裸奔


本教程概述了阿秒条纹理论，这是一种泵浦探针方案，用于提取过去十年中广泛使用的电离过程的定时信息。重点放在库仑激光耦合 (CLC) 术语的起源上，这对于解释条纹延迟至关重要。在正确理解各种出版物中的 CLC 术语如何相互关联后，我们将能够分析在哪种情况下，条纹延迟可以分为测量引起的 CLC 术语和“纯”电离延迟，以及在哪种情况下这种分裂可能会破裂的条件。因此，我们解决了长期存在的问题，即作为 CLC 项和“纯”电离延迟之和的广泛应用的条纹延迟解释的有效性。
