“…Plasma evolution was investigated by Fu et al 108 using three fast-imaging cameras that captured three successive plasma images from the same laser-induced Ti-alloy plasma. The early plasma evolution stage, when the plasma and surrounding gases have a strong interaction, was investigated.…”

“…4–9 However, the subtle fluctuations of laser energy, surrounding ambiance, and sample morphology would lead to unstable plasma, causing large spectral signal fluctuations in LIBS measurement. 10,11 The large spectral fluctuations bring about large errors in LIBS analysis, impeding the improvement of precision and accuracy and hence limiting its large-scale application and commercialization. Therefore, the improvement of spectral signal stability has great significance.…”

“…2 However, LIBS was still limited by its relatively low quantitative performance due to the difficulties in modelling the complex relationship between spectral intensities and the element concentration caused by matrix effects and high signal uncertainty. [3][4][5][6] How to efficiently handle the complex relationship has become a non-trivial task to improve the capacity of LIBS quantitative analysis.…”
