摘要：

In this study,a stand-off and collinear double pulse laser-induced breakdown spectroscopy(DP LIBS) system was designed,and the magnesium alloy samples at a distance of 2.5 m away from the LIBS system were measured.The effect of inter-pulse delay on spectra was studied,and the signal enhancement was observed compared to the single pulse LIBS(SP LIBS).The morphology of the ablated crater on the sample indicated a higher efficiency of surface pretreatment in DP LIBS.The calibration curves of Ytterbium(Y) and Zirconium(Zr) were investigated.The square of the correlation coefficient of the calibration curve of element Y reached up to 0.9998.
