摘要：

We have applied laser-induced fluorescence diagnostics to expanding recombining barium plasmas produced by laser ablation. For relatively modest ablation laser energy fluences (∼102-103 W cm -2), we have measured neutral barium leading edge density gradients of 1012-0.5×1013 cm-3 cm-1 and cloud expansion velocities of ∼106 cm s-1, consistent with recent results of ablation studies in copper [R.
