Nanoscale Femtosecond Coherent Radiation and Spatiotemporally Shaped free electron Wavefunction
Wu Wen, Jing Li, Yunquan Liu
We study tunable nanoscale femtosecond coherent radiation based on a coupled nanowire pair (CNP) structure that is excited by a strong laser. The structure functions as a nanoscale…
