A review on the study of Laser-Induced Shock Wave Plasma Spectroscopy (LISPS), which was developed by the present authors, has been presented. It is demonstrated that characteristic laser plasma can be produced when a pulse laser (N₂ laser, XeCl excimer laser, TEA CO₂ laser and YAG laser) is focused on a solid target under reduced pressures (around 1-10 Torr), and this plasma has many characteristics favorable as the source of the emission spectrochemical analysis. On the basis of the results obtained by the experiments using unique time-resolved spatial distribution of the dynamical emission, it is proved that this plasma are excited by a shock wave induced by the laser ablation. Practical applications to the quantitative emission anlysis are also presented.
