Abstract
Spectroscopic method was used to observe pulse laser induced ablation plume of graphite. Time-integrated emission spectrum of ablation plume of graphite was measured for laser wavelengths of 1064 nm, 532 nm and 308 nm. TOF measurements were also made to determine both the species of plume constituents and their velocity as they move from the target surface. By analyzing the obtained spectrum, several species were identified, i.e., at least a carbon ion, a carbon atom and a C2 molecule. Dynamic vibrational temperature was estimated for the obtained spectra of swan bands based on the statistical mechanics. The ablation mechanisms were discussed considering the non-equilibrium nature of the plume.
