论文摘要
AttSond测量结果揭示了来自原子，分子和凝结物质的照片电离动力学的新物理见解。但是，在这样的时间尺度上，即使是小时抖动也可以显着降低泵探针测量的时间分辨率。在这里，我们提出了一种新型技术，可以从一种良好的ATTSOND干涉技术中检索Attsond延迟，该技术被称为通过两次透明过渡的干扰（Rabbitt）重建Attsosend theing的重建，该技术不受计时抖动的影响，并显着改善了您的前部实验的精确性。我们将这种新技术称为短乌龟的计时 - 耶和华未受影响的拉比时间延迟提取方法。使用这种乌龟技术，我们可以测量氩和霓虹灯之间与先前测量的完全一致的电离时间延迟。乌龟技术允许无泵探针时间延迟稳定并且无脉冲脉冲可以分辨率分辨率，因为只需要稳定的XUV频率梳子作为泵。例如，这将更容易地实现Fels的Attsond测量，从而为Attosecond科学提供了有价值的工具。在这里，我们还为乌龟配合使用MATLAB代码，并提供适当的引用。
Attosecond measurements reveal new physical insights in photo ionization dynamics from atoms, molecules and condensed matter. However, on such time scales even small timing jitter can significantly reduce the time resolution in pump-probe measurements. Here, we propose a novel technique to retrieve attosecond delays from a well established attosecond interferometric technique, referred to as Reconstruction of Attosecond Beating By Interference of Two-photon Transition (RABBITT), which is unaffected by timing jitter and significantly improves the precision of state-of-the-art experiments. We refer to this new technique as the Timing-jitter Unaffected Rabbitt Time deLay Extraction method, in short TURTLE. Using this TURTLE technique we could measure the attosecond ionization time delay between Argon and Neon in full agreement with prior measurements. The TURTLE technique allows for attosecond time resolution without pump-probe time delay stabilization and without attosecond pulses because only a stable XUV frequency comb is required as a pump. This will more easily enable attosecond measurements at FELs for example and thus provide a valuable tool for attosecond science. Here we also make a MATLAB code available for the TURTLE fit with appropriate citation in return.
