The ionization of atoms has been studied for centuries, and it has been experimentally demonstrated in atomic gases. Analogously, ionization can be achieved in solids, and specifically dielectrics. The free electrons which result from ionization generate a plasma, whose ignition produces modifications of the material, i.e., structural damages . Properly engineering these modifications allows for structuring glasses, giving rise to the field of micromachining . Specifically, modifications made on the glass surface can result in the removal of the material, which is referred to as optical ablation [3,4].
