摘要：

One-dimensional imaging laser-induced fluorescence spectroscopy has been used for in-situ measurements of spatial distributions of YO molecules produced during the ArF-laser ablation of YBa2Cu3O7-x in vacuum and oxygen gas environment. The time-integrated angular distribution of particles ejected in vacuum has a cos(n) theta form, where 11 < n < 13. When oxygen gas was introduced, YO molecules were confined in a smaller volume, and temporal changes of their spatial distribution were interpreted in terms of blast-wave formation.
