FIG. 7.
Dynamic data of the (200) peak diffraction intensity from 50 nm Bi on 4 μm Prolene support for two different laser fluences of 45 mJ/cm2 (data #1) and 30 mJ/cm2 (data #2). For the dataset #1 the raw data is depicted for reference. Binning in 150 fs intervals produces data which is fitted by a piecewise exponential decay (see text). Fit parameters of dataset #1: tau = (443 ± 27) fs, T0 = (0 ± 12) fs, a = 1.0 ± 0.014, c = 0.03 ± 0.017; dataset #2: tau = (880 ± 170) fs, T0 = (43 ± 34) fs, a = 1.038 ± 0.013, c = 271 ± 38. The color coding of the binned data points represents the statistical weight, which is the number of single shots summed in a bin. Error bars attached to the binned data are deduced from the standard errors of the mean and for reference only. They are not used during evaluation. The Y-error of the single raw data points is around ±0.2. The X-axis is arbitrary in offset and here calibrated by dataset #1.
