Animated sequence of snapshots of the collapse of a sub-surface void
Animated sequence of snapshots showing an enlarged view of the collapse of one of the sub-surface voids present in the target prior to the irradiation with the 2 nd laser pulse. The snapshots are shown for 0 to 100 ps with a time resolution of 5 ps. The atoms are colored by their potential energies, so that most atoms in the crystalline part of the target are blue, the atoms in the melted part are green, and the atoms on free surfaces are red. Several snapshots from this animation are also shown in Fig. 7 of the paper.
