Chinese Academy of Sciences and the University of Dusseldorf in the study of high brightness hard X-ray source has been progress

Due to its wide application in materials and biological research, high-intensity X-ray source has always been the target pursued by international related scientific research fields. Energetic radiation, synchrotron radiation, X-ray free electron (XFEL), etc. can produce high-intensity X-ray sources. Ultra-short super-laser through different mechanisms of interaction, in various frequency bands from THz to gamma rays to produce high-brightness ultra-short electromagnetic radiation source.

Chinese Academy of Sciences Shanghai Institute of Optics and Fine Mechanics strong laser state physics laboratory and the German University of Dusseldorf, recently in the international physics journals, "Physical Review Letters" reported the use of high-contrast ultrashort super-laser and micro-plasma Channel Interactions Produce High-Brightness X-Ray Schemes.

Ultra-strong laser channel electronically pulled out the wall, the acceleration in the laser field, high-energy electrons in the laser field in the lateral movement of the radiation can be very strong X-ray. With this new mechanism, the energy of X-ray radiation is about 20 keV and the number of photons per pulse is close to 1011. The X-ray source has good collimation with a brightness of 5 × 1023photons / s / mm2 / mrad2 / 0.1% bandwidth. An important solution for generating extremely bright X-rays for this important frequency band (~ 20KeV) is presented. The State Key Laboratory of Strong Field Laser Physics is preparing to conduct experiments on the ultrashort superlattice laser device in the laboratory.
