The Advanced Attosecond Laser Facility (Dongguan portion) project, a major national science and technology infrastructure, has made significant progress, with the pouring of the first raft slab for the No. 1 attosecond device building completed recently. This is the world's second large-scale scientific installation of attosecond lasers, which, upon completion, will provide strong support for cutting-edge basic research and industrial applications in multiple disciplines, such as physics, chemistry, materials, information, and biomedicine.

A second is the shortest time scale that mankind can grasp, with the help of advanced a second laser facility generated by the a second laser pulse, scientists can "shoot" the transient process of high-speed movement of electrons. The advanced attosecond laser facility is like an "ultra-high-speed camera" that can capture the "dynamic image" of electrons and record quantum properties, magnetic changes, chemical reactions and phase transitions of materials and other phenomena related to the movement of electrons.

The Advanced Attosecond Laser Facility, with a total layout of 10 beamlines and 22 application terminals, is scheduled to be built in five years. The six beamlines to be constructed in Dongguan are under the responsibility of the Institute of Physics of the Chinese Academy of Sciences (IPS), while the other four beamlines will be constructed in Xi'an, Shaanxi Province, under the responsibility of the Xi'an Institute of Optical Precision and Mechanical Research (XIPMR) of the Chinese Academy of Sciences.
The advanced attosecond laser facility (Dongguan part) project has a total construction area of about 38,000 square meters, which is constructed by CCA Group Construction and Development Co. Ltd. The construction includes attosecond device building, experimental center, precision optics machining center, power station, power station and so on. The raft slab poured this time is the "vibration shield" for the extremely precise ultra-fast optical experiment platform of the No.1 sub-second device building, which will lay a solid foundation for the subsequent construction of the main structure.
