| Abstract: | In this paper, the time-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 stark broadening and the intensity of emission spectral line. The temporal evolution property of the electron temperature and the electron density of the laser-induced Ni plasma was finally discussed according to the experimental results. |
