Laser-induced breakdown spectroscopy (LIBS) using double-pulse irradiation with Nd:YAG and CO(2) lasers was applied to the analysis of a polystyrene film on a silicon substrate. An enhanced emission signal, compared to single-pulse LIBS using a Nd:YAG laser, was observed from atomic carbon, as well as enhanced molecular emission from C(2) and CN. This double-pulse technique was further applied to 2,4,6-trinitrotoluene residues, and enhanced LIBS signals for both atomic carbon and molecular CN emission were observed; however, no molecular C(2) emission was detected.
利用钕
钇铝石榴石激光器和二氧化碳激光器进行双脉冲辐照的激光诱导击穿光谱法（LIBS）被应用于分析硅基衬底上的聚苯乙烯薄膜。与使用钕：钇铝石榴石激光器的单脉冲LIBS相比，观察到来自碳原子的增强发射信号，以及来自C₂和CN的增强分子发射。这种双脉冲技术进一步应用于2,4,6-三硝基甲苯残留物，观察到了碳原子和分子CN发射的增强LIBS信号；然而，未检测到分子C₂发射。
