Because the sequence of events that leads to laser ablation, which may be defined as the collective ejection of matter (ions, atoms, clusters, nanoparticles, etc.) following irradiation by ultrashort, intense bursts of light, is formidably complex, the usual analytical tools of theoretical physics are unable to account for the whole spectrum of relevant processes taking place in the target, and thus cannot provide a thorough understanding of the physical mechanisms that underlie the phenomenon, as well as the physical nature of the structural modifications inflicted to the system following the absorption of energetic photons, notably in the so-called heataffected zone. To make the problem even more difficult, the process takes place on an unusually wide range of length and timescales. In view of these difficulties, computer simulations are, in spite of their limitations, an excellent route to understanding the physics of ablation [1 …
