The dynamics of both a laser-ablation plume and ambient gas were studied by visualizing their density distributions by laser-induced fluorescence imaging spectroscopy. A deep dip was formed in the density distribution of the ambient gas. The depth of the dip was almost 100% immediately after irradiation of the ablation laser pulse. The size of the dip expanded with time. At a long delay time after the irradiation of the ablation laser pulse, the ambient gas returned to the dip and slowly filled it. The location of the dip corresponded to that of the plume ejected from the target. This means that the high pressure of the plume removed the ambient gas, and the plume and the ambient gas located exclusively. In addition, we observed the formation and propagation of a compressed layer around the dip.
