| Research Abstract |
An enhanced near-field scattered from nanostructures is localized to the nano-scale zone, and is then used for nano-ablation processing of a variety of advanced functional materials. This report presents theoretically and experimentally the characteristics of near-field and nano-ablation in terms of femtosecond laser polarization, irradiation angles, scattering structures, scattering materials, work materials. Near-fields from plasmonic scattering and Mie scattering are clearly explained. In addition to the enhanced near-field processing, the mechanism of surface ripples formed by the interference of the incident femtosecond laser and the scattered far-field light is well explained by using the 3D FDTD method. The nano-patterned surfaces fabricated these methods can potentially be used for surface photonic devices.
