Abstract
A 193 nm excimer laser is used to ablate a Bi2CaSr2Cu2O9 superconductor and samples of Bi2O3, CaO, CuO, and Sr(OH)2⋅8H2O. Emission spectra generated during ablation are presented. These emissions are from simple atomic and diatomic species. Our observations show that the emission can be used to characterize the bulk material.Keywords
