Measurement and analysis of titanium monoxide spectra in laser-induced plasma

We present results including measurement and analysis of titanium monoxide. Pulsed, nanosecond Nd:YAG laser radiation is used in a typical laser-induced breakdown spectroscopy arrangement to record the spectra. This scheme provides experiments analogous to pulsed laser deposition tactics and allows for time-resolved spectroscopic analysis. The computed spectra are generated from a new, accurate line-strength file that allows us to accurately predict gamma (A(3)Phi -> X-3 Delta) and gamma' (B-3 Pi -> X-3 Delta) spectral signatures. We infer temperature on the order of 3600 +/- 700 K and 4200 +/- 800 K at time delays of 52 and 72 mu s, respectively. Current interest in this work includes titania (TiO2) nanoparticle generation for thin film applications. (C) 2012 Optical Society of America
