Outline of Final Research Achievements

The non-thermal effect on femtosecond laser ablation has been focused on for development of high-precision micromachining technique. We focus on a time-resolved grazing-incidence small-angle X-ray scattering (GI-SAXS) technique to study the ablation dynamics.We have developed the GI-SAXS system and measured the image of the Bragg peak from a gold-deposited optical grating sample on CCD camera. In contrast, scattering from a post-ablated crater on a gold plate was hidden in thermal noise of the camera.
Whereas the GI-SAXS measurement is limited by the noise of the camera, we succeeded time-resolved ultraviolet and near-infrared reflectivity measurements using double pump pulse. In addition, we also succeeded reflectivity measurement using polarized neutrons and proton-polarized sample, which reveal surface and interface structure of multi-layered film. We believe the this technique would be used to reveal chemical change of femtosecond-laser-irradiated polymer surface.
