Abstract

This paper focuses on the interpretation of the origin of the continuum radiation in Laser Induced Plasma(LIP) emission spectra, a subject that has received little consideration in the literature when compared to theanalysis of the line emission spectrum. The understanding of the spectral peculiarities observed immediatelyafter the laser pulse, when the continuum radiation prevails on discrete emission lines, can be extremelyimportant to retrieve the initial conditions of LIP and to correlate the produced plasma to the ablationmechanism. In this work, in addition to a qualitative interpretation of the LIP continuum in the initial stage ofexpansion, a methodology is proposed for a better measurement of the atomic temperature in the expansionstage of the LIP. Such methodology is based on the analysis of the combined Boltzmann and Planck plots. Theresults obtained stress once again the importance of considering non equilibrium effects in the initial stage ofLIP expansion.
