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.
