Intensities of emission spectra of laser-induced alloy-aluminum plasma, with use of neodymium YAG laser (laser pulse energy is 6~10 J), were experimentally studied in air atmosphere. Emission spectra of laser-induced aluminum plasma of 6~10 J energy were obtained. Relationship between spectral line intensity and laser energy were analyzed. Experimental results show that signal intensity of spectral line increases with increasing of laser energy. In addition, half width of spectral line was obtained by Lorentz linear fitting of plasma spectra, in order to calculate electron density. Electron density and signal intensities will decrease gradually with increasing of shock time.
