The ICCD photographic investigation of the plasma reveals three common phases to the expansion: forward motion, deceleration and the stopping of the leading edge of the plume, followed by an apparent reflected shock within the plume which propagates backward and finally a secondary forward propagation at a time around 100 μs. The forward motion and deceleration of carbon plasma are plotted in our case in Fig. 4 and by the first peak of CN in Fig. 3 and Fig. 5. The apparent reflected shock associated with the evolution of the second peak of CN is also shown in Fig. 3 and Fig. 5.
