Inner-shell Ionization X-ray Laser and Hollow Atom X-ray Laser

摘要

An ultrafast inner-shell ionization process generated by high brightness x-rays is studied. The process plays an important role not only for the optimization of the physical processes of an inner-shell ionization x-ray laser, but also for the formation of hollow atoms. The hollow atom x-ray laser has a clear advantage over the conventional inner-shell ionization method.
