A simple scheme is proposed and experimentally confirmed to generate X-ray free-electron lasers (XFELs) consisting of broadband and narrowband beams with a controllable intensity ratio and a large photon-energy separation. This unique two-color XFEL beam will open new opportunities for investigation of nonlinear interactions between intense X-rays and matter.
提出了一种简单方案并通过实验验证,以产生由宽带和窄带光束组成的X射线自由电子激光(XFEL),其强度比可控且光子能量分离大。这种独特的双色XFEL光束将为研究强X射线与物质之间的非线性相互作用带来新机遇。
