Evolution of the squared diameter versus the neperian logarithm of the energy of irradiation for a single pulse irradiation. The scanning electron microscope (SEM) images show the impact aspect for both samples for the lowest irradiation fluence (F1p = 0.25 J/cm2) corresponding to the value displayed by the red line: ln(E/E0) = 2 (with E0 = 1 µJ).
