In order to characterize the laser ablation process as it relates to the deposition of high T/sub c/ superconducting thin films, optical emission spectra produced during ArF excimer laser ablation of the high T/sub c/ superconductor YBa/sub 2/Cu/sub 3/O/sub 7/ were studied. The population of excited states within the gas phase blow-off material depends strongly on excimer laser fluence at 193 nm. Ablation using relatively low excimer laser fluences produces a significant fraction of YO in the gas phase. The plasmas derived from ablation of targets made from the high T/sub c/ material are similar to plasmas observed from ablation of the individual components BaCO/sub 3/, CuO, and Y/sub 2/O/sub 3/.
