When a short and intense light pulse that is focused onto a sample surface is absorbed by the surface, a small amount of the material can be removed (ablated), vaporized and ionized to finally form a plasma plume that emits light. The light has a characteristic spectral structure relating to the plasma and the sample composition. The ablation abilities and plasma formation after the interaction of the intensive laser pulse with a material surface have been observed very soon after the invention of the laser. This knowledge, combined with optical emission spectroscopy methods, later resulted in a new analytical technique: laser induced breakdown spectroscopy (LIBS) [1].
