摘要

Plasma dynamics within and after the laser pulse irradiation at different ambient gas pressures in air were investigated from the laser ablated Al plasma (1064 nm, 15 ns, and 1.8 J/mm²) using an optical streak camera. At 50 and 400 Pa, front positions of the fast moving part fitted well with the Drag model once the laser started. At 1 atm, multiple radiation regions caused by the laser-target ablation and air breakdowns were observed.
