The attoclock is an important tool offering the capability to time resolve tunneling ionization. In this article, we systematically study the influence of nonadiabatic, nondipole and quantum effects on the attoclock signal. In contrast to previous studies, where a single peak offset angle is used to represent the attoclock information, we survey the whole momentum distribution of the attoclock signal. We find that nonadiabaticity affects the overall momentum distribution, the quantum effect of intercycle interference changes substantially the attoclock offset angle, and the nondipole effect plays a negligible role in the attoclock signal in the polarization plane. The present study is essential for a quantitatively correct interpretation of the attoclock experimental results.

attoclock 是一个重要的工具，它提供了时间分辨隧道电离的能力。在本文中，我们系统地研究了非绝热、非偶极子和量子效应对 attoclock 信号的影响。与以前的研究相反，在以前的研究中，单个峰值偏移角用于表示 attoclock 信息，我们调查了 attoclock 信号的整个动量分布。我们发现非绝热性影响整体动量分布，周期间干涉的量子效应显着改变阿托钟偏移角，非偶极效应对极化平面阿托钟信号​​的作用可以忽略不计。本研究对于定量正确解释 attoclock 实验结果至关重要。
