Abstract

We present time-resolved spectroscopy of laser-produced plasmas achieved with a 500 fs resolution. Time history of Al K-shell emission from hot solid density plasmas produced by the interaction of an intense subpicosecond laser pulse (150-400 fs, 0.53 μm, 5×10¹⁸ W/cm²) with a thin free-standing foil target (500-1000 Å) appears to change drastically with laser pulse duration, the X-ray emission duration decreasing with the heating pulse duration. We report here what we believe to be the first observations of subpicosecond thermal X-ray emissions (Al He_α, 500-700 fs) in laser-produced plasmas. Such results are of interest for applications to the observation of ultrafast phenomena in matter.
