摘要：

The life of laser-induced plasma is usually in the μs region, and it is necessary to study the temporal evolution of the plasma in order to optimize the signal detection. Calibration curve is the basis of quantitative analysis, which closely relates to the sensitivity and accuracy. The plasmas were induced by a focused, pulsed laser. The emission spectra of plasmas were then dispersed by an Echelle spectrograph and detected by an intensified charge-coupled device (ICCD). Graphite was the major constituent of the sample, and Ca, Al, Na, K elements were added to pellet the sample respectively. The spectra including the emission lines of Ca, Al, Na, K elements were presented. The temporal evolution curves of the plasmas were obtained via the experimental system of using the gating periods of 100 ns of ICCD. The calibration curves of the lines intensities were obtained. The calibration curves were also analyzed, whose slope are different for the spectra line of the same element of the sample at different wavelength.
