Abstract

The invention discloses a full-optically driven full-coherence table type X ray free electron laser which obtains temporal and spatial full-coherence X ray free electron lasers by using a full-optical driving method. For both HH (higher harmonic) injection source and high-energy electron injection source, the same laser system is adopted for driving, thus the output of full-coherence table type Xtype free electron lasers can be produced. The full-coherence 'water window' band (even the keV-magnitude attosecond light source) is very important in the fields of physics, chemistry, life science,material science and the like.

Description

technical field [0001] The invention relates to an X-ray free electron laser, in particular to an all-optical driven all-coherent desktop X-ray free electron laser. [0002] Based on the high-performance high-energy electron beam obtained by the laser wake field acceleration mechanism, the highly coherent seed pulse in the 10 nm band is obtained by using the atomic high-order harmonic of the strong laser field, and injected into the free electron XUV laser to study how to obtain a stable and fully coherent electron beam. X-ray free electron laser output. Ultrafast X-ray coherent radiation in the high-brightness water window band or even keV level is of great significance to physics, chemistry, life science, material science, etc. Background technique [0003] The interaction between ultra-powerful femtosecond laser and atoms can produce coherent light sources in the femtosecond and attosecond extreme ultraviolet (XUV) bands, enabling humans to detect and manipulate new phen...
