Coherent synchrotron radiation by excitation of surface plasmon polariton on near-critical solid microtube surface
Bifeng Lei, Hao Zhang, Daniel Seipt +5
Coherent synchrotron radiation (CSR) is crucial for the development of powerful ultrashort light sources. We present a mechanism for generating CSR in the form of generalised super…
Pulse duration dependence of material response in ultrafast laser-induced surface-penetrating nanovoids in fused silica
Guodong Zhang, Na Li, Hao Zhang +7
The focused ultrafast laser, with its ability to initiate nonlinear absorption in transparent materials, has emerged as one of the most effective approaches for micro-nano processi…
Leaky surface plasmon-based wakefield acceleration in nanostructured carbon nanotubes
Bifeng Lei, Hao Zhang, Cristian Bontoiu +6
Metallic carbon nanotubes (CNTs) can provide ultra-dense, homogeneous plasma capable of sustaining resonant plasma waves-known as plasmons-with ultra-high field amplitudes. These w…
100s TeV/m-Level Particle Accelerators Driven by High-density Electron Beams in Micro Structured Carbon Nanotube Forest Channel
Bifeng Lei, Hao Zhang, Cristian Bontoiu +5
Solid-state materials, such as carbon nanotubes (CNTs), have the potential to support ultra-high accelerating fields in the TV/m range for charged particle acceleration. In this st…
