便携式激光诱导击穿光谱最新研究进展

As a new and rapid material composition analysis technique, laser-induced breakdown spectroscopy (LIBS) has been proven to have great application potential in an increasing number of industrial fields. However, due to the existence of noisy and harsh detection environments in field operations or industrial sites, new and higher requirements have been put forward for the size of instruments and equipment and their ability to resist harsh environments. In recent years, the development of new lasers has further promoted the process of LIBS instrumentation, making it gradually move from the laboratory to industrial applications and also making the LIBS system gradually tend to be instrumented, specialized, and portable. This article reviews the development process of portable LIBS, summarizes and classifies the latest research progress of various laser light sources (small Nd:YAG solid-state lasers, diode-pumped solid-state lasers, microchip lasers, fiber lasers, and fiber energy transmission schemes) applied to portable LIBS systems, discusses the basic problems existing in current portable LIBS, and looks forward to its future development trends.

作为一种新型快速的物质成分分析技术，激光诱导击穿光谱（laser-induced breakdown spectroscopy, LIBS）已经在越.来越多的工业领域中被证明具有巨大的应用潜力。然而，由于野外作业或工业现场嘈杂恶劣检测环境的存在，对仪器设.备的大小尺寸和抗恶劣环境的能力提出了新的更高的要求。近年来，新型的激光器的发展进一步促进了LIBS 仪器化的.进程，使得其逐渐从实验室迈向工业应用，同时也使得LIBS 系统逐渐趋于仪器化、专业化、便携化。本文综述了便携.式LIBS 的发展历程，对各种激光光源（小型Nd: YAG 固体激光器、二极管泵浦固体激光器、微片激光器、光纤激光器以.及光纤传能的方案）应用于便携式LIBS 系统的最新研究进展进行了综述和分类讨论，探讨了当前便携式LIBS 存在的.基本问题，并对其未来发展趋势进行了展望。
