In order to analyze and detect the elemental distribution of natural jade sample surface, reheating orthogonal dual-pulse laser-induced breakdown spectroscopy was adopted to obtain two-dimensional (2D) surface elemental mapping of jade sample. The influence of time interval between two pulses to the signal intensities and signal to background ratio was studied experimentally. Variation relationship between spectral intensity and pulse energy of the reheating laser was discussed. Under optimized experimental condition, the surface scanning analysis of the natural jade within the scope of 36 mm×10 mm was implemented. With the lateral resolution of 30 microns, 2D distribution mapping of trace element iron was obtained. It was demonstrated that reheating orthogonal dual-pulse laser-induced breakdown spectroscopy technique was able to be applied to realize the detection of trace element in natural jade and improve detection sensibility which was helpful for jade identification. This surface elemental mapping technique could be used to achieve the analysis of component distribution of jade and other solid samples which will have nice application prospects.
