The objective of this technical note is to present the results of employing a new, to the best of our knowledge, temporary synchronization device to the study of laser-induced plasma spectroscopy in a multi-pulse regime. By providing a means of controlling the time delay and the reading window of the spectrometer, this device allows the user to distinguish among the emissions from independent micro-pulses and groups of micro-pulses. Using this method, it is possible to optimize the reading of the spectra by choosing the most appropriate time delay and duration values of the spectral reading window.
