Figure 5
The pulse duration was estimated to be below 400 fs from a non-thermal melting experiment in crossed-beam geometry. The time axis shows delay of the probing X-ray pulse with respect to the laser pulse. The black squares are the experimental data whereas the blue curve is the model from Lindenberg et al. (2005). The red dashed line is the same model but convoluted with a 400 fs Gaussian curve. The noise in the experimental data is due to photon statistics. The data have been smoothed to a five-point weighted average. |
