| The Atomic Emission Spectroscopy is the most widely application method of qualitative and quantitative analysis of element. Comparing with other spectroscopy analysis technology, the atomic emission spectroscopy of laser is nearly nondestructive analysis, and has unique advantages in the analysis of the element which is hard to evaporate and stimulate. The research of laser plasma has comprehensive application foreground in film preparation, laser isotope separations, medicine and biology. At present, the atomic emission spectroscopy of laser used infrared laser most, and the related analysis were always theoretical, semi-quantitative, qualitative analysis. The research about the application of ultraviolet laser and quantitative analysis was very little。The principles of the atomic emission spectroscopy , the formative process , the spectral characteristics, the processes and methods of quantitative analysis by spectrography were given. The real-time atomic emission spectrum of the arc plasma (Cu) has been measured by micro-fiber optic spectrometers. The relation of the excitated temperature and time was obtained. The excitation temperature of the arc plasma was comparatively stable after the arc has been ignited about thirty seconds.The atomic emission spectrum of laser plasma (Cu) was obtained by grating spectrometer. The spectrum has been used to definite the experimetal condition. The atomic emission spectrum of laser plasma (HPb59-1) was obtained on that condition. Analysised the line shape of the spectra lines of the alloy by XeCl laser induced breakdown . Drawed the working curve, analyzed the content RSD of Ni and Fe.Study confirmed that the ultraviolet laser applying to atomic emission spectroscopy is feasible, and can improve the least sampling quantity of quantitative analysis .
