title: X-ray sources based on subpicosecond-laser-produced plasmas.
abstract: The production of an efficient user friendly ultrafast x-ray source requires an understanding of the role of the various factors which affect the x-ray emission. Here we examine several issues which control the source brightness and the pulse duration. Picosecond time-resolved, high spectral resolution spectroscopy is used to study plasmas produced by a subpicosecond laser pulse with intensity between 1016 W/cm2 and 5 × 1018 W/cm2.
