Facility Tour: Advanced Attosecond Laser Infrastructure (AALI, Dongguan)

Advanced Attosecond Laser Infrastructure (AALI) is designed to be a comprehensive ultrafast electron dynamics research facility, characterized primarily by attosecond temporal resolution and high spatiotemporal coherence of its light sources. The facility aims to achieve tracking, measurement, and manipulation of electron motion and electron correlations. Based on the characteristics of electron motion, it seeks to explore evolutions of material and/or quantum states as well as the laws of non-equilibrium processes from the perspective of electromagnetic interaction theory, providing a unique tool for breakthroughs in fundamental research in areas including atomic/molecular physics, condensed matter physics, quantum mechanics, materials science, chemistry, and life sciences. The project of AALI is administrated by the Institute of Physics and the Xi'an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences (CAS). AALI has two sites, which are located in Dongguan City, Guangdong Province, and Xi'an City, Shaanxi Province.

AALI features 10 ultrafast beamlines and 22 application endstations, covering wavelengths in the extreme ultraviolet, soft X-ray, and terahertz radiation bands, and offering multiple specialized characteristics such as high repetition rates, high pulse energies, short pulse durations, and narrow bandwidths. The project is expected to be completed within 5 years, and the construction includes beamlines, endstations and auxiliary facilities as well as buildings and clean rooms, with a total building area of approximately 66,700 square meters.
