Abstract

Time-resolved spectroscopy of the plasma state produced by laser ablation of Bi2Sr2Ca1Cu2 oxide, an amorphous solid of the same composition, and unreacted mixture of the components is reported. The difference in the spectra among the samples indicates that the ablation products depend on the chemical structures of the irradiated samples. Effects of the ambient gas revealed that ionic species in the electronic ground states are mainly generated at the initial stage of the ablation, while atomic species are produced by collisions between the surrounding-gas molecules and plasma plume.
