Schlieren images and optical emission spectroscopy data. Schlieren images taken at a 400 ns, b 600 ns, and c 800 ns after the peak of the drive laser. The box in panel b shows the region over which the density power spectra, shown in Fig. 3a–c, are calculated. Panels df show experimental emission spectra (solid black lines) from the regions marked by × in panels ac, along with the best-fit theoretical spectrum (blue-dashed lines). The parameters given correspond to the plotted theoretical spectrum. Panels gi show corresponding profiles of temperature (red crosses), density (blue circles), and turbulent velocity (green squares) across the region indicated by a dashed line in panel a, as inferred from the optical emission spectroscopy. The error bars represent a 10% deviation between the calculated and measured emission spectra
