摘　　要：以波长1064 nm的Nd:YAG调Q激光束为激发光源,对铜、镁铝合金和钢等金属材料的激光诱导等离子体光谱(Lips)进行了实验探测,并分析了延迟时间、环境气体等因素对元素光谱特性的影响。适当的延迟时间和氩气环境能显著地改善谱线的信噪比,从而提高元素含量分析的精度。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
