摘要：
A LIBS experimental set-up is designed and evaluated to obtain the spatio-temporal distribution of atomic and molecular emission signals after the ablation of samples with different amounts of Ca and F. This analysis revealed separated temporal and spatial regions that maximized the atomic and molecular emission signals, respectively. Therefore, these distributions are investigated to elucidate the origin of the CaF molecular excited species, and to evaluate the development of an optimized method for the measurement of CaF molecular signals, which are related to the concentration of F in the sample.
