摘要：

The Langmuir probe was used to study erosion plume resulting from ablation of a tantalum target in vacuum with excimer laser (308 nm) radiation. The spatial and temporal dependencies of electron and ion probe currents were obtained in real time. Relying upon a series of dependencies of electron probe currents on the value of probe potential,; electron temperature of different plume regions was taken at various distances from the target. It was established that the plume electron temperature is non-uniform. The ion concentration in the plume determined at various distances from the target.
