| Abstract: | The emission spectral intensities of laser-induced alloy aluminum p lasma,with the use of a neodymium glass laser (laser pulse energy is about 25J), were experimentally studied in argon atmosphere.The effects of atmosphere pressu re,height from the observed location of the plasma to the surface of the sample and power density of the laser on the signal intensities of emission spectra we re discussed. |

| Keywords: | laser induced-plasma atmosphere pressure power density spectral int ensity |
