Abstract
Time-resolved sum frequency generation is an established tool to investigate the ultrafast vibrational dynamics with surface and interface specificity, which can be extended to the regime of electronic transitions using a white light continuum as demonstrated previously by studies of liquid interfaces. We expand this technique to the investigation of solid single crystal samples. In particular, we demonstrate the potential of electronic sum frequency generation by probing the non-equilibrium dynamics at excitonic resonances in ZnO with a sensitivity as small as 0.6% and with a time resolution of 160 fs.
