| Abstract: | In this paper, the spatial-resolved emission spectrum of Ni atom in laser induced Ni plasma was measured in the wavelength region from 350nm to 600nm. The electron temperature and the electron density of plasmas were calculated from the measured intensity and stark broadening of emission spectral line respectively. The spatial evolution property of the electron temperature and the electron density were finally discussed according to the experimental results. |
