he dynamics of tho laser ablation plume, including the shape of the plume, are understood to be important for good film depositions and and understanding of the dynamics are necessary for a process control to be effective. Recent experiments indicate that the substrate heater is a strong control parameter. The purpose of this paper is to analytically interpret these results from the point of view of shock dynamics and to compare with numerical flow simulations.
