The “Dalian Light Source”, developed by the Chinese Academy of Sciences, has issued the world’s most extreme ultra-violet free electron laser pulse. A single picosecond laser pulse generates 140 trillion photons, making it the world’s brightest fully tunable EUV free Electronic laser light source.

In this kind of extreme ultraviolet light irradiation, the region almost all atoms and molecules are “nowhere to hide.” Therefore, the “Dalian light source” can be used to observe the physical and chemical processes associated with combustion, the atmosphere and clean energy. sn74lvcu04a

Wang Enge, vice president of the Chinese Academy of Sciences, said that this is the Chinese Academy of Sciences and China has a very high display of the major scientific and technological achievements, 90% of the equipment by the Chinese independent research and development, marking China occupies the world leader in this field Status, will greatly promote China in the energy, optics, physics, biology, materials, atmospheric haze, lithography and other important areas of research to enhance the level.

Free electron laser is a new generation of advanced light source, is also the world’s advanced countries competing development important direction in the scientific research, advanced technology, national defense science and technology development has important application prospects.

“Dalian Light Source” is China’s first large-scale free electron laser scientific research user device, is the world’s only operating in the extreme ultraviolet band of free electron laser device, is the world’s brightest extreme ultraviolet light source.

The laser can work in femtosecond or picosecond pulse mode, you can use SASE (self-amplifying spontaneous emission) or HGHG (self-amplified radiation), which can be used in the ultra-violet region is completely continuous adjustable, with complete coherence; High gain harmonic amplification) mode operation. xc4020xl-3pq160c

“Dalian light source” project by the National Natural Science Foundation of the major national instrument special funding, by the Chinese Academy of Sciences Dalian Institute of Chemical Physics and Shanghai Institute of Applied Physics jointly developed. Project in October 2014 officially started construction in Dalian Changxing Island, the end of September 2016 to complete the installation of light for the first time, creating a similar large-scale scientific device construction in China’s new record.
