Fig. 2

The vertical dashed line shows the shock-wave arrival time at the ablator/LCO interface. The light gray band shows the calculated reflectance assuming a uniform volume fraction of carbon nanoparticles, where the absorption increases with the thickness increase of shocked material via shock propagation; the bandwidth is due to uncertainties in the dielectric function of liquid carbon, and accordingly in the estimate of the absorption depth. We assume loss due to the formation of carbon nanoparticles begins around 50 ps, where the reflectance of the >16 GPa data (5 shot average) significantly deviates from the 10–16 GPa data (9 shot average)—see Supplementary Discussion for further details. Source data are provided as a Source Data file.
