Time-resolved spectroscopic study of the KrF laser-induced plasma plume created above an YBaCuO superconducting target

Abstract

The laser-induced plasma plume created above an YBaCuO superconducting target 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 from temporal evolution of spatially resolved spectroscopic measurements.
