I003 Long-short double pulse laser-induced breakdown spectroscopy for carbon detection in steel samples

摘要

Long-short double pulse laser-induced breakdown spectroscopy (LS-DP-LIBS) employed to detect the carbon element in solid and liquid steel samples. The important issues for the industrial application of LIBS are investigated in this work, which include the carbon excitation in steel, the influences of CO2, the quantitative analysis and the escape phenomenon of carbon [1].
