    • Abstract

       

      Time resolved optical emission spectroscopy is employed to study the expansion dynamics of C2 species in a graphite plasma produced during the Nd : YAG ablation. At low laser fluences a single peak distribution with low kinetic energy is observed. At higher fluences a twin peak distribution is found. It has been noted that these double peak time of flight distribution splits into a triple peak structure at distances ≥17mm from the target surface. The reason for the occurrence of multiple peak is due to different formation mechanisms of C2 species.
