| Abstract | Time resolved optical emission spectroscopy is employed to study the expansiondynamics of C2 species in a graphite plasma produced during the Nd : YAG ablation. At low laserfluences a single peak distribution with low kinetic energy is observed. At higher fluences a twinpeak distribution is found. It has been noted that these double peak time of flight distribution splitsinto a triple peak structure at distances >_ 17mm from the target surface. The reason for theoccurrence of multiple peak is due to different formation mechanisms of C2 species |
