Title: Spectral Characterization of Laser Induced Plasma from Titanium Dioxide
Author: Radhakrishnan, P; V P N Nampoori; Girijavallabhan, C P; Nandakumaran, V M; Dann, V J; Mathew, M V
Abstract: Optical emission from TiO2 plasma, generated by a nanosecond laser is spectroscopically analysed. The main chemical species are identified and the spatio-temporal distribution of the plasma parameters such as electron temperature and density are characterized based on the study of spectral distribution of the line intensities and their broadening characteristics. The parameters of laser induced plasma vary quickly owing to its expansion at low background pressure and the possible deviations from local thermodynamic equilibrium conditions are tested to show its validity
