摘　　要：本文在350-600 nm波长范围内测定了激光烧蚀Ni等离子体中Ni原子的时间分辨发射光谱.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中电子温度、电子密度的时间演化特性.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.
