Abstract.

Formation mechanisms of atomic and oxide ions in a plume (laser-induced plasma) produced by the laser ablation of a YBa2Cu3O7-x (YBCO) target was studied by time-of-flight (TOF) analysis. The dependence of the TOF spectra on the laser wavelengths (266 nm and 1064 nm) was examined to elucidate photochemical phenomena in the plume. Significant changes in the relative enrichment of metal oxide and oxygen ions as well as their TOF distributions were observed by the injection of an oxygen jet to the plume, which induces reactive scattering of the YBCO plume and the oxygen jet.
