摘要

We have carried out a comparison of the influence of two different wavelengths, 1.06 and 2.94 μm for Nd:YAG and Er:YAG lasers, respectively. This was performed under He or air environments in terms of plasma properties and spectrochemical analysis of several elements in aluminum alloys. The results show that these parameters induce important variations in the generated plasma, in terms of temperature and analytical measurements. This study was performed in order to allow a better comprehension and control on the implementation of laser-induced breakdown spectroscopy.
