On-chip high energy photon radiation source based on microwave-dielectric undulator
Fuming Jiang, Xinyu Xie, Chengpu Liu +1
A new on-chip light source configuration has been proposed, which utilizes the interaction between microwave and a dielectric nanopillar array to generate a periodic electromagneti…
High-quality femtosecond laser surface micro/nano-structuring assisted by a thin frost layer
Wenhai Gao, Kai Zheng, Yang Liao +9
Femtosecond laser ablation has been demonstrated to be a versatile tool to produce micro/nanoscale features with high precision and accuracy. However, the use of high laser fluence…
Chirp control of directional current in monolayer graphene by intense few-cycle laser
Erheng Wu, Qiang Zhan, Zhanshan Wang +2
The residual current density in monolayer graphene driven by an intense few-cycle chirped laser pulse is investigated via numerical solution of the time-dependent Schrödinger equat…
Generation of nonlinear vortex precursors
Yue-Yue Chen, Xun-Li Feng, Chengpu Liu
We numerically study the propagation of a few-cycle pulse carrying orbital angular momentum (OAM) through a dense atomic system. Nonlinear precursors consisting of high-order vorte…
