Abstract
Laser-driven ultrafast hard x-ray sources based on Kα emission from solid targets are nowadays a powerful tool to monitor ultrafast lattice dynamics in condensed matter [1]. Such point-like sources are of great interest in biomedical imaging where spatial resolution and image quality can be highly improved [2]. Therefore, the development of high-flux Kα sources with a small size remains important for the ultrafast x-ray community. Especially, with the routinally obtained now femtosecond laser performances (intensities I > 1018 W/cm2 with high contrast pulses >108), it is possible to explore interaction regimes where Kα emission can be strongly enhanced.
