Abstract

The laser ablation pressure at 0.44 μm was measured in planar Al targets at irradiance up to 2×10¹⁴ W/cm². The lateral energy transport and the drilling effect were avoided by adopting relatively large focal points and a smoother laser beam. It was found that plasma corona size becomes larger during the laser interaction, and the distance between the absorption region and the ablation surface increases with time. The measured scaling showed a good agreement with analytical models and the data could be used for an experimental database of ablation pressure scaling to study the equation of state.
