| Abstract: | In this paper, the Stark Brodening of the emission spectra from the plasma produced by using 308nm Excimer laser to ablate the solid Mg sample was measured with an Optical Multichannel Analyzer. The dependence of the Stark broadening on the time delay and the pressure of the buffer gas was investigated. The time evolution character of the electronic density in the laser induced plasma was obtained and the influence of the pressure of buffer gas on the poperty of laser induced plasma was discussed. |
