Abstract

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 plasmas 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.

Key words: laser-induced plasma spectroscopy, delay time, ambient atmospheres, elemental recognition
