Figure 1. Transmission at 860 nm versus time after X-ray pump pulse.

Figure 1

Data points are normalized to the transmitted intensity before X-ray excitation and are the average of 100 shots. Error bars are the standard deviation of 100 shots and are largely due to laser/X-ray pulse timing jitter. Dashed curve: Gaussian time profile of X-ray pulses. Solid curve: integral, which matches data at the transition region. Inset (top): scattering geometry, with GaAs surface at the intersection of the X-ray and laser beams. Inset (bottom): transmission at longer times, fit to an exponential decay with a lifetime of 1.1 ns.
