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。
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.
