Description

‘Seeing means believing’ as the old axiom says. Every year around 50 000 scientists worldwide use X-ray photon beams at synchrotron and X-ray Free-Electron Laser (XFEL) facilities to image the structure and motion of matter. X-ray studies on protein crystallography and X-ray driven catalysis in biomolecules became reality with the development of synchrotron light sources. The advert of XFELs has enabled biological imaging with femtosecond X-ray pulses, which is nowadays a key instrument for structural biology. Recently, attosecond lasing was demonstrated at several XFELs and first user experiments on charge migration and photoionization started. In this talk, I will discuss the present state-of-the-art of ultrashort pulse generation in XFELs and review some recent technological developmenst.
