Stimulated Raman scattering in the degenerate regime
Yao Zhao, Suming Weng, Zhengming Sheng +1
Stimulated Raman scattering (SRS) in plasma in the degenerate regime is studied theoretically and numerically. Different from normal SRS with the non-degenerate eigen electrostatic…
Control of transverse motion and X-ray emission of electrons accelerated in laser-driven wakefields by tuning laser spatial chirp
H Xiao, M Chen, S M Weng +3
A method is proposed to control the transverse motion and X-ray emission of an electron beam in a laser driven wakefield by tuning the laser spatial chirp. The dispersion of a tran…
Mapping electromagnetic fields structure in plasma using a spin polarized electron beam
X. Y. An M. Chen, J. X. Li, S. M. Weng +3
We propose a scheme to mapping electromagnetic fields structure in plasma by using a spin polarized relativistic electron beam. Especially by using Particle-in-Cell (PIC) and elect…
Simultaneous polarization transformation and amplification of multi-petawatt laser pulses in magnetized plasmas
Xiaolong Zheng, Suming Weng, Zhe Zhang +4
With increasing laser peak power, the generation and manipulation of high-power laser pulses becomes a growing challenge for conventional solid-state optics due to their limited da…
Suppression of parametric instabilities in inhomogeneous plasma with multi-frequency light
Yao Zhao, Suming Weng, Zhengming Sheng +1
The development of parametric instabilities in a large scale inhomogeneous plasma with an incident laser beam composed of multiple-frequency components is studied theoretically and…
Controlling injection using a magnetic field to produce sub-femtosecond bunches in the laser wakefield accelerator
Q. Zhao, S. M. Weng, M. Chen +5
It is shown that electron injection into a laser-driven plasma bubble can be manipulated by applying an external magnetic field in the presence of a plasma density gradient. The do…
