In this project, we propose to merge the precision of near-field microscopy with the latest possibilities of extremely nonlinear sub-cycle terahertz optics for the first time. Based on an unprecedented combination of a high-power multi-THz (1 THz = 10^12 Hz) source with an apertureless scattering-type near-field optical microscope (SNOM), we will design atomically strong, phase-locked, few-cycle electromagnetic transients localized in the few-nanometer near-field region of a metallic tip. The intense electromagnetic waveforms will be utilized to explore a novel realm of non-perturbative sub-cycle nanooptics.

在这个项目中，我们建议合并近场显微镜的精度与最新的极端非线性子周期太赫兹光学的第一次。基于高功率多太赫兹（1 THz = 10^12 Hz）源与无孔散射型近场光学显微镜（SNOM）的前所未有的组合，我们将设计原子强、锁相、少周期电磁瞬变局部化在金属尖端的几纳米近场区域。强烈的电磁波将被用来探索一个新的领域的非微扰子周期纳米光学。
