| Abstract: | Laser-induced plasma spectroscopy of metal materials including copper,magnalium and steel was investigated.The effects of delay time and ambient atmospheres on the emission characteristics of laser-induced plasma spectroscopy were studied.Experimental results show that proper delay time and ambient atmospheres of argon can notably enhance signal-to-noise ratio of spectra,thus the accuracy of elemental content analysis was improved. |
| |
| Keywords: | laser-induced plasma spectroscopy delay time ambient atmosphere elemental recognition |
