Outline of Final Research Achievements

We have succeeded in observation of the details of the temporal evolution of the ablating surfaces induced the femto-second laser by using the shingle-shot soft x-ray laser probe system. The ablation front with a solid or the melted surface and the expansion front with thin film structure were observed. Especially the sample of Au, the expansion front separated from the ablation front was thin, dense and smooth, therefore it works as the beam splitter for the soft x-rays at the time within 1 ns after the laser irradiation. The surface roughness of expansion front was better than a few nm, and the formation of nano-bubble structures were expected below the ablation front. In addition we have observed the result of the theoretical simulation for the femtosecond ablation process within 100 ps by using the molecular dynamics (MD) simulation.
