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 the spectra on space-resolved x-ray spectrographs. The plasma to be probed and the x-ray backlighter source are produced by different beams of the same frequency-doubled Nd laser. Kα spectroscopy probes F-like to He-like ions and Lα,β spectroscopy is a diagnostic of higher atomic number ions stripped into configurations around the Ca-like structure. Measurements of dense matter radiatively heated at temperatures around 50–100 eV in laser-irradiated multilayered targets or x-ray heated samples evidence the effect of radiative heating on the temperature gradient in the target. The space and time-resolved measurements of the corona of a low temperature aluminum plasma are presented.
