Program Description
The successful lasing of the Linac Coherent Light Source (LCLS) has opened a new era for photon science, enhancing the x-ray brightness by ten orders of magnitude over third generation synchrotron light sources. Despite being a well established experimental tool, research on x-ray free-electron lasers (XFELs) is very active, fueled by the users' demands for new modes of operation and more precise x-ray diagnostics and control.
In this talk I will discuss several research activities aimed at shaping the spectral and temporal properties of XFELs. In particular I will describe our recently developed twin-bunch FEL for the generation of two-color pulses and discuss its recent application to x-ray pump/x-ray probe experiments at LCLS. Finally I will present our ongoing efforts in laser-shaping and laser-slicing of electron bunches, aimed at shaping XFEL pulses at the femtosecond and attosecond time-scales.
