摘　　要：在350-600nm波长范围内测定了激光烧蚀Ni等离子体中Ni原子的空间分辨发射光谱.由发射光谱线的强度和STARK展宽分别计算了等离子体电子温度和电子密度,并由实验结果讨论了激光等离子体的空间演化特性.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.
