Abstract

We study warm dense matter formed by subpicosecond laser irradiation at several 1019 W/ cm2 of thin Ti foils using x-ray spectroscopy with high spectral (E/ΔE∼15,000) and one-dimensional spatial (Δx=13.5 μm) resolutions. TiKα doublets modeled by line-shape calculations are compared with Abel-inverted single-pulse experimental spectra and provide radial distributions of the bulk-electron temperature and the absolute-photon number Kα yield in the target interiors. A core with ∼40 eV extends homogeneously up to ten times the laser-focus size. The spatial distributions of the bulk-electron temperature and Kα yield are strongly correlated.
