Time-resolved spectroscopy was used to study the plasma emission induced by a 1064 nm, 10 ns pulsed laser ablation titanium during the early phase of between 60–200 ns in an atmospheric environment. The line intensity evolution of Ti III and Ti II was analysed in terms of the delay time, as well as the plasma temperature and electron density, based on the observed spectra. The Stark broadening for two Ti III lines at 237.4986 and 241.3989 nm was measured. Since the self-absorption of the lines was not observed in our experiment, its influence on the lines was assumed to be negligible. Moreover, a modified semi-empirical approach was used to calculate the Stark broadening for the two lines and generally good agreement was obtained between the theoretical results and experimental data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
