Characterization of the KrF laser-induced plasma plume created above a BiSrCaCuO target

Abstract

The laser-induced plasma plume created above a BiSrCaCuO superconducting target by a KrF laser beam (248 nm) is investigated by time-resolved spectroscopy. The influence of the oxygen partial pressure on the ejection velocities of the ablated species and on the relaxation of atomic and molecular excited species is particularly studied.
