Abstract

Fast imaging and sensitive spectroscopic investigations of laser ablation plume propagation reveal fundamental collisional phenomena relevant to film growth by pulsed laser deposition and optimized cluster growth via laser vaporization. Two phenomena are detailed. The first involves the splitting of the ablation plume into distinct high- and lowenergy components as a weak shock front froms during ablation into a low-density background gas.
