Figure 2 Schematic diagram of a desktop free electron laser device based on laser wake field acceleration
With funding from the National Major Scientific Research Instrument Development Project (Approval Number: 11127901), the research team of the State Key Laboratory of Strong Field Physics, Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made breakthroughs in the research of miniaturized free electron lasers based on laser accelerators Progress, the first to complete the experimental verification of the desktop free electron laser principle in the world
Free electron laser is currently the best technical way to produce high-brightness coherent light sources in the X-ray band
The wake field acceleration mechanism driven by the super-strong and ultra-short laser provides a new way for the development of miniaturized electron accelerators
In order to complete the scientific goals of the national major scientific research instrument development projects and stay ahead of the international competition, the research team of the Shanghai Institute of Optics and Mechanics has fully carried forward the spirit of "10 years of sharpening a sword" and conducted eight years of research
"Nature" published an article to evaluate the work, ".
The research team will further increase the output power and photon energy of the free electron laser
