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