Recent experimental results on ion beams produced in high-intensity laser–solid interactions indicate the presence of very intense electric fields in the target. This suggests the possibility of efficiently heating a solid material by means of the

An experimental and numerical analysis of the ionization dynamics of a freely expanding nanosecond laser-produced plasma is given. Point-projection X-ray absorption spectroscopy with picosecond time-resolution is used to provide a spatio-temporal map

Two types of Bragg Fresnel multilayer zone plates operating in the keV range have been investigated for X-ray laser-plasma imaging. Elliptical on-axis and off-axis Bragg Fresnel multilayer zone plates were characterised. With the on-axis zone plate a

We present measurements of the samarium $(Z=62)$ $M$-shell absorption band around 11 \AA{} (1.1 keV) at electron temperatures between 5 and 20 eV. Using point projection absorption spectroscopy, we measured the absolute transmission of an x-ray probe

Diagnostic by Kα and Lα,β absorption spectroscopy leads to information on the ionization state, the electronic temperature, and matter density of laser‐produced plasmas. In particular, a mapping of the ionic populations is possible by recording
