Abstract


Pulsed laser induced plasma technique is a powerful and available method, and has been widely used in many important fields such as material process, superconductor thin film preparation, nano-technique and trace element analysis. Although many experimental and theoretical researches have been carried out on the laser produced plasma dynamics, the time and spatial-resolved spectral properties in recent years, it is still an unsolved problem because the forming of laser produced plasma is a very complicated process not only related to the properties of the laser and buffer gas but also the physical-chemical properties of the solid sample. The investigations on the mechanism of interaction between the laser and the solid surface and the dynamics of the laser induced plasma should be performed in deep depth. The study on the emission spectral from the laser induced plasma provides a most effective method to explore the dynamics of the laser induce plasma.Based on the previous studies reported on the investigation on the dynamics of the laser induced plasma, we have studied the time and spatial resolved properties of the laser-produced plasma by measuring the emission spectra from the laser-induced Ni plasma. We have measured the time and space-resolved emission spectral of the laser-induced Ni
