在可见光区域内研究激光引发的等离子体光谱法(LIPS).发现不同靶材产生的等离子体的空间形状和发光颜色不-样,而且不管激光以多大角度入射于靶,产生的等离子体都垂直于靶面向外辐射.不同靶材产生的等离子体谱线分析的最佳位置与待分析元素的原子量有关,放置在最佳位置时可以得到信噪比高的待测元素的辐射谱.此外在混合物靶材引发的等离子体中还发现ArI离子的特征谱线,如在紫铜和镀Zn的Fe中发现578.352m的ArI离子特征谱线,而在黄铜中发现578.155m的ArI离子特征谱线.

Some results of the laser induced plasma spectra in the visible range are presented. It is noticed that the spatial shape and fluorescent color of the induced plasma are different for different target materials, and the induced plasma beam is perpendicular to the target despite whether the laser is oblique to the target The optimum location in the plasma for spectral analysis is different for various targets which depends on the atomic mass. And a characteristic spectrum of the ArI (578.352 nm) is discovered in the plasma spectra of red copper and the Fe doped with Zn, while ArI (578.155 nm) is discovered in the plasma spectra of brass.
