| Research Abstract |
We have formed periodic nanostructure on hard thin films with femtosecond laser pulses, of which size is below diffraction limit of light. This phenomena was not under stood in detail because it was ultrafast nonlinear interaction between matter and light. In this study, I demonstrated that (1) the nanostructure was formed on dielectric materials and semiconductors by local fields and surface plasmon polaritons excited with femtosecond laser pulses and (2) the shape of the nanostructure could be controlled by changing the distribution of the local fields.
