摘要

We demonstrate how ultrafast electron microscopy can be used to quantitavely analyse the modal structure of plasmonic nano-resonators and to coherently manipulate the optical near-field by multicolor laser pumping scheme - enabling the generation of complex beating patterns between different plasmonic modes.
