1962年6月，在马里兰州大学举行的第10届国际光谱学学术讨论会上，弗雷德·布雷奇描述了他最初令人鼓舞的光谱化学测量方法，该方法使用红宝石“脉泽”诱导等离子体。使用激光诱导的“火花”作为光谱化学等离子体源的想法是非常有吸引力的，其潜在的优点现在是众所周知的：不需要样品制备;可以检查任何相的样品，导电或不导电;远程测量是可能的;可以获得空间信息;快速，同时多元素分析是可能的。在过去的35年里，激光诱导等离子体光谱学在三个明显的增长和下降的兴趣时期得到了广泛的研究。在过去五年中，该领域的活动水平有所提高，这主要是由于探测技术的不断改进和激光源的日益可靠。现在看来，激光诱导等离子体光谱学将发现有用的应用在元素过程监测和便携式半定量元素分析仪。该技术的基本矩阵敏感性可能会限制其作为通用分析工具的使用。本文回顾了1997年的部分文献。
At the Xth Colloquium Spectroscopicum Internationale, held at the University of Maryland in June, 1962, Fred Brech described his initial encouraging spectrochemical measurements using a ruby `maser'-induced plasma. The idea of using a laser-induced `spark' as a spectrochemical plasma source is extremely attractive and the potential advantages are now very well known: no sample preparation is needed; a sample of any phase may be examined, electrically conducting or not; remote measurements are possible; spatial information can be obtained; and rapid, simultaneous multi-element analysis is possible. For the past 35 years, laser-induced plasma spectroscopy has been widely studied during three obvious periods of growing and declining interest. The last five years have seen a renewed level of activity in the field, largely the result of ever improving detection technologies and increasingly reliable laser sources. It now appears likely that laser-induced plasma spectroscopy will find useful applications in elemental process monitoring and in portable semi-quantitative elemental analyzers. The fundamental matrix sensitivity of the technique may limit its use as a general-purpose analytical tool. This review examines selected literature of 1997.
