Abstract
Laser-induced Breakdown Spectroscopy(LIBS) based on atomic emission spectral technology is a kind of convenient and sensitive approach for the qualitative and quantitative detection of elements. In this paper, the mechanism, detecting element types, detection limit and the recent progress of LIBS technology are reviewed. The progress of LIBS technology in component testing for solid, liquid and gas samples is expounded in detail. The applications of LIBS in the environment test, food security, biological and medicines, material sciences, military and space fields are also presented. Finally, the challenges and problems for the LIBS technology in high power and stable laser sources and accurately quantitative analysis method are discussed.
