| Abstract: | Laser-induced plasma technology is an important topic of the research on interaction between laser and material for a long time. The experiment system of laser induced plasma is researched and designed. Nd：YAG laser is used to induce Aluminum sample to produce plasma. And the Aluminum plasma emission spectra under dif？ferent energies are obtained. The element types contained in Aluminum sample and the changing relationship be？tween spectral line intensity and laser energy are analyzed. Experimental results show that the Aluminum sample contains Fe and Mg elements and with the increase of laser energy, spectra intensity increases obviously. |
