Extended Data Fig. 1: Characterization of the temporal double slit with a short (225 fs) probe pulse.
a, Experimental intensity reflectivity (blue line) for a 2.3 ps separation between the time slits, as a function of the probe delay. This is fitted with the model in Fig. S2A (dashed red line). b, Reflectivity for a linear variation of the slit separation (horizontal axis) measured as a function of the probe delay with one of the pumps (vertical axis). c, Intensity dependence of the maximum achievable reflectivity for the two time slits driven by pump 1 (incident at 54°) and pump 2 (incident at 66°). The reflectivity saturates reaching a maximum value of 0.6.
