摘要：

The plume dynamics for excimer laser ablation of Y-Ba-Cu-O in an O 2 atmosphere have been studied using streak photography and spectroscopy. At pressures approximately-greater-than 1 mbar the expansion resembles a blast wave driven by the ablation products with mixing and reaction at the contact surface. A simple model for the plume range is developed which shows agreement with experiments.
