When a laser radiation is focused on a sample (solid, liquid and gas), its electromagnetic energy is transformed in to electronic excitation (free electron, plasmons). If the laser energy exceeds a characteristic threshold (depending on sample features and laser parameters), evaporation, atomization, and partial ionization of the sample will result. Laser induced plasma (LIP) is defined as the generation of a totally ionized gas, a plasma, that practically is a ‘gas’ of charged particles. Therefore a short-pulse high power laser beam focused onto a sample converts a finite volume of sample instantaneously into its vapor phase constituents in an expanding plasma cloud. The high electron density and the high temperature sustain a plasma that then will rapidly evolve through a series of kinetic mechanisms. The study of the temporal and spatial evolution of LIP in different environments by the spectroscopic techniquesleads to the required knowledge useful for a wide range of application fields (i.e. chemical analysis, nanoparticles and nanostructures production).
