The article discusses the use of ultrafast photoemission spectroscopy and photon engineering techniques in the study of quantum materials. These techniques allow scientists to observe the development of electronic band structures and their occupancy over time, providing insights into non-equilibrium characteristics. The National Synchrotron Radiation Research Center in Taiwan is working on enhancing time-resolved spectroscopic methodologies, including the development of a time-resolved photoemission spectroscopy system and a time-resolved angle-resolved photoemission spectroscopy system. These systems aim to deepen our understanding of the electronic and dynamic characteristics of substances and their relationship with fundamental physical attributes. The article highlights the design and specifications of the Tr-ARPES setup, including the laser source, optics, and photon flux generation. The system offers high energy and temporal resolution, making it a powerful tool for studying quantum materials and driving innovation in various scientific and technological fields.
