The Effect Of Spectral Lines Choice For Depth Profiling LIPS Experiment

Laser-induced Plasma spectroscopy (LIPS) is a useful method for determining the elemental composition of various materials but for long time it have been mainly restricted to qualitative and quantitative analysis of samples material. Recently LIPS is applied in addition to depth-profile analysis. In this paper we were trying to investigate the differences in the depth profile, obtained adopting femtosecond LIPS, that may occur on changing the spectral lines chosen for the analysis. The used femtosecond laser has pulse duration of 130 fs, wave length of 795 nm and pulse energy 200 μJ. It was found that the differences observed were not significant as long as the spectral lines chosen are fulfilling the LIPS spectral lines conditions.
