Omnidirectional optical attractor in structured gap-surface plasmon waveguide.

Scientific reports

Sheng C, Liu H, Zhu S, Genov DA.
PMID: 27001451
Sci Rep. 2016 Mar 22;6:23514. doi: 10.1038/srep23514.

An optical attractor based on a simple and easy to fabricate structured metal-dielectric-metal (SMDM) waveguide is proposed. The structured waveguide has a variable thickness in the vicinity of an embedded microsphere and allow for adiabatic nano-focusing of gap-surface plasmon...

Demonstration of self-truncated ionization injection for GeV electron beams.

Scientific reports

Mirzaie M, Li S, Zeng M, Hafz NA, Chen M, Li GY, Zhu QJ, Liao H, Sokollik T, Liu F, Ma YY, Chen LM, Sheng ZM, Zhang J.
PMID: 26423136
Sci Rep. 2015 Oct 01;5:14659. doi: 10.1038/srep14659.

Ionization-induced injection mechanism was introduced in 2010 to reduce the laser intensity threshold for controllable electron trapping in laser wakefield accelerators (LWFA). However, usually it generates electron beams with continuous energy spectra. Subsequently, a dual-stage target separating the injection...
