Chinese successfully developed the world's most extreme ultraviolet light bright

In January 15, and the development of China Academy of Sciences "Dalian light source" issued on the 15 extreme ultraviolet free electron laser pulse the strongest in the world, a single picosecond laser pulse produced 140 trillion photons, become extreme ultraviolet free electron laser source of the world's most bright and fully adjustable wavelength.

In this very area under the irradiation of ultraviolet light, almost all atoms and molecules are nowhere to hide". Therefore, the "Dalian source" can be used for observation and combustion, air and clean energy related physical and chemical processes.

Chinese Vice President Wang Enge said, this is Chinese Academy of Sciences and China and a high degree of major scientific and technological achievements display device, 90% instruments were Chinese by independent research and development, marking the China occupy the leading position in the world in this field, will greatly promote the China in energy, optics, physics, biology, material, atmospheric haze, lithography a number of important areas to enhance the level of research.

The free electron laser is a new generation of advanced light source on the most advanced international, is an important direction to the development of advanced countries in the world, it has an important application prospect in scientific research, advanced technology, national defense science and technology development.

"Dalian light" is the first large Chinese free electron laser science research on the user device, is one of the world's only run in the free electron laser EUV extreme ultraviolet light, but also the world's most bright.

According to reports, the "Dalian source" wavelength in the extreme ultraviolet region completely adjustable, with full coherence; the laser can work in femtosecond or picosecond pulse mode, you can use the SASE (self amplified spontaneous emission (HGHG) or high gain amplification of harmonic mode).

"Dalian has been a major source of" project of National Natural Science Foundation of China National Instrument grant, jointly developed by the Chinese Academy of Sciences, Dalian Institute of Chemical Physics and Shanghai Applied Physics research. The project in Dalian Changxing Island on October 2014 officially started construction, the end of September 2016 completed the first installation of light, creating a new record China similar large scientific equipment construction.
