Figure 4
The SFG signal generated for two different time delays between the weak pulse from the bending magnet (orange) and the intense femtosecond light-pulse from the laser (red) is marked as a blue arrow. In the lower image the bending magnet pulse arrives sooner by a distance of cΔt resulting in a change of position of the generated signal (blue arrow). After calibration, the position of the SFG signal is a direct measure of the relative time between the laser pulse and the light pulse from the bending magnet.
