本文提出一套基于可调谐真空紫外飞秒光源的新型trARPES系统，在1 MHz重复频率下实现21 meV能量与<360 fs时间分辨率，并集成EUV HHG光束线提供优异的时间-带宽可调谐性。

摘要：

时间分辨和角分辨光电子能谱（trARPES）允许直接映射电子能带结构及其在飞秒时间尺度上的动态响应。在此，我们展示了一套新的ARPES系统，由一种新的基于光纤的真空紫外（VUV）范围飞秒光源驱动，能够访问大多数材料的完整第一布里渊区。我们展示了Au(111)、多晶Au、Bi2Se3和TaTe2的trARPES数据，在1 MHz的高重复频率下，实现了21 meV的能量分辨率和<360 fs的时间分辨率。该系统集成了极紫外（EUV）高次谐波产生（HHG）光束线，实现了时间-带宽分辨率的极佳可调谐性。

英文摘要：

Time and angle-resolved photoemission spectroscopy (trARPES) allows direct mapping of the electronic band structure and its dynamic response on femtosecond timescales. Here, we present a new ARPES system, powered by a new fiber-based femtosecond light source in the vacuum ultraviolet (VUV) range, accessing the complete first Brillouin zone for most materials. We present trARPES data on Au(111), polycrystalline Au, Bi2Se3 and TaTe2, demonstrating an energy resolution of 21 meV with a time resolution of <360 fs, at a high repetition rate of 1 MHz. The system is integrated with an extreme ultraviolet (EUV) high harmonic generation (HHG) beamline, enabling excellent tunability of the time-bandwidth resolution.
