| Outline of Final Research Achievements |
In order to discuss the nanometer-scaled precise ablation phenomena induced by femtosecond laser irradiation, we constructed the femtosecond laser pump and the soft x-ray probe time resolved imaging system. From the reflective imaging, we succeed to reveal the expansion process of the exfoliated film associated with the femtosecond laser ablation. In addition, it has found that the vertical shape of the exfoliated films is similar to the intensity profile of the incident laser beam used for the laser ablation.
Moreover, by using the soft x-ray interferometry, the formation process of the exfoliated film that has formed within less than one nanosecond, and the formation process of the ablation crater has successfully observed.
