Abstract
The shape of the plasma plume induced by KrF-laser irradiation of Y−Ba−Cu−O, Cu−O, and Cu targets in O2 and N2 atmosphere was investigated by time-integrated photography. The dependence on laser fluence, spot size, and pressure of the ambient gas was studied. Special emphasis was put on the ablation of YBCO in O2 atmosphere under experimental conditions that are typical for thin-film deposition.
