Temporal emission of magnesium lines from laser-induced plasma and use in calibration curves

In this study, Nd:YAG laser pulse is used to ablate the Magnesium sample for laser induced breakdown spectroscopy analysis. The emission lines are plotted for ionic and atomic element of Mg I and Mg II respectively. The emission lines of Mg I and Mg II were recorded at wavelength of 279.55 nm, 280.27 nm and 285.21 nm. The analysis including the different of gate delay, determination of signal to background ratio and calibration curve of different concentration of magnesium is discussed in details.
