Laser-induced breakdown spectroscopy (LIBS) using double-pulse irradiation with Nd:YAG and CO2 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.
