摘　　要：超快激光由于极高的时间分辨特性,已成为相关大科学装置建设的重要内容之一。介绍怀柔科学城已建设完成的综合极端条件实验装置中阿秒激光实验站的主要内容,该实验站基于少周期飞秒脉冲及高次谐波技术,可输出光子能量达100 eV的极紫外(XUV)相干辐射和脉冲宽度仅为86 as的孤立阿秒脉冲(IAP),并配备角分辨光电子能谱仪(ARPES)、光电子显微镜(PEEM)、冷靶反冲离子动量谱仪(COLTRIMS)等多种时间分辨终端设备,可以在原子或亚原子尺度上开展从飞秒到阿秒时间分辨的物理、化学、生物、材料等体系的超快动力学研究。Objective With the development of ultrafast laser technology,especially the generation of high power few-cycle femtosecond laser pulses with their carrier-envelope phase(CEP)locking,attosecond laser pulses based on high-order harmonic generation(HHG)via interaction between high power femtosecond lasers and noble gas have become a leading direction in ultrafast sciences.In 2001,the attosecond pulse train and isolated attosecond pulse(IAP)were realized successively by Pierre Agostini’s team and Ferenc Krausz’s team respectively,and the generation and measurement of attosecond pulses made scientists master a powerful tool to look into ultrafast processes inside materials at unprecedented precision,thus giving birth to a new field and research direction:attosecond science.Characterized by unique specifications such as very short pulse duration with high photon energy and sound coherence,the attosecond light beam provides unprecedented new tools that can go deep into the interior of atoms to measure their electronic dynamic behavior,thus triggering a revolution in basic research.Therefore,the 2023 Nobel Prize in Physics was awarded to three physicists,Pierre Agostini,Ferenc Krausz,and Anne L’Huillier,for their pioneering contributions to the experimental method of generating attosecond light pulses to study the electron dynamics in matter.Many countries have invested a lot of funding to carry out relevant studies.In particular,Europe soon established the attosecond alliance.Meanwhile,Ferenc Krausz led the establishment of the Max Plank center for attosecond science including scientists from China,Japan,the Republic of Korea,Australia,and other countries.Meanwhile,it is worth mentioning that under the proposal of G.Mourou and other scientists,the European Union started to conduct a research program on the extreme light infrastructure(ELI)early in 2006.This program included the ELI-attosecond light physical science(ELI-ALPS)facility located in Hungary with attosecond light sources as the main beams,in which attose
