Description
The pulse duration of the X-ray free-electron laser (XFEL) relies on the pulse duration of the light source, which commonly is an electron bunch. The energy and the current distributions of the electron bunch can be manipulated by using the laser heater in the purpose of generating attosecond pulse duration electron bunch. Therefore, the resultant electron bunch current profile after the bunch compressor chicane right behind the laser heater is programmable by the laser parameters. We performed the electron bunch shaping experiment by using the laser heater at PAL XFEL. The parameter dependencies of the laser heater shaping are discussed based on analytical and numerical approaches.
