Laser ablation being the basic process for many prominent applications of lasers in present day high technology, medicine, and other fields, its basic physics is reviewed in this chapter. In order to distinguish the fundamental, laser–material interaction from any secondary effects, we concentrate on ultrashort laser pulses (≅100 fs duration) at comparably low intensities, below the commonly indicated threshold for massive material removal. It is shown that – for these conditions – the principal light/matter coupling occurs via multiphoton excitation of electrons into the conduction band or the vacuum.
