Study of the laser ablation process of metals by using the soft x-ray laser

The surface nano-structures such as the ripple and bubble like form produced by short pule laser are applicable for the novel functional materials. We are studying the dynamics of the laser ablation process of metals by using the soft x-ray laser probe at the wavelength of 13.9 nm. The transient thin-film structures was observed in the several materials under the condition that near the ablation threshold. It was quite thin, dense and smooth so that it works as the soft x-ray beam splitter. The precise observation of the laser ablation dynamics leads to the control of the surface modification.International Conference on X-ray Lasers 201
