摘要：

The laser-induced plasma plume created above an YBaCuO superconducting target irradiated by a KrF laser beam (248 nm) is investigated by time-resolved spectroscopy. High-resolution spectra are obtained and ejection velocities of ablated species are deduced as a function of the ambient oxygen pressure. Preliminary results on the preparation of YBa2Cu3O7-x thin films on 〈100〉 SrTiO3 substrates, by the excimer laser ablation of a stoichiometric 1 : 2 : 3 target, are presented. © 1990.
