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.

从纳米结构散射的增强近场被定位到纳米尺度区域，然后用于各种先进功能材料的纳米烧蚀加工。本文从理论和实验两个方面研究了飞秒激光的偏振态、入射角、散射结构、散射材料、工作材料等对近场烧蚀和纳米烧蚀的影响。等离子体散射和米氏散射的近场被清楚地解释。除了增强近场处理外，利用三维FDTD方法很好地解释了入射飞秒激光与散射远场光干涉形成表面波纹的机理。这些方法制备的纳米图案化表面可以潜在地用于表面光子器件。
