摘要：

We present analysis of superposition spectra following laser-induced breakdown ( LIB) of methane. Both hydrogen-beta and hydrogen-gamma lines contain discernible contributions from diatomic carbon emissions for time delays of 1 to 2 mu s from pulsed, 8 ns, infrared Nd:YAG laser radiation LIB. Analysis of the atomic lines and molecular C-2 spectra reveal electron and molecular excitation temperatures of typically 13,000 and 5000 K, respectively. (C) 2012 Optical Society of America
