Generation of high power spatially-structured laser pulses via forward Raman amplification in plasma
Zhi-Yu Lei, Su-Ming Weng, Min Chen +2
Spatially-structured light with tunable intensity, wavelength, and spatiotemporal profiles has demonstrated significant potentials for fundamental and applied science, including th…
Towards the generation of petawatt near-infrared few-cycle light pulses via forward Raman amplification in plasma
Zhi-Yu Lei, Zheng-Ming Sheng, Su-Ming Weng +2
Light amplification towards extremely high power in the infrared regime remains a significant challenge due to the lack of suitable gain media. Here we propose a new scheme to ampl…
Dense polarized positrons from beam-solid interactions
Xing-Long Zhu, Wei-Yuan Liu, Tong-Pu Yu +4
Relativistic positron sources with high spin polarization have important applications in nuclear and particle physics and many frontier fields. However, it is challenging to produc…
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…
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…
Efficient injection of radiation-pressure-accelerated sub-relativistic protons into laser wakefield acceleration based on 10 PW lasers
M. Liu, S. M. Weng, H. C. Wang +6
We propose a hybrid laser-driven ion acceleration scheme using a combination target of a solid foil and a density-tailored background plasma. In the first stage, a sub-relativistic…
Preliminary Measurements for a Sub-Femtosecond Electron Bunch Length Diagnostic
M. K. Weikum, G. Andonian, N. S. Sudar +8
With electron beam durations down to femtoseconds and sub-femtoseconds achievable in current state-of-the-art accelerators, longitudinal bunch length diagnostics with resolution at…
Cascaded acceleration of proton beams in ultrashort laser-irradiated microtubes
H. C. Wang, S. M. Weng, M. Murakami +4
A cascaded ion acceleration scheme is proposed by use of ultrashort laser-irradiated microtubes. When the electrons of a microtube are blown away by intense laser pulses, strong ch…
Dense blocks of energetic ions driven by multi-petawatt lasers
S. M. Weng, M. Liu, Z. M. Sheng +4
Laser-driven ion accelerators have the advantages of compact size, high density, and short bunch duration over conventional accelerators. Nevertheless, it is still challenging to s…
A compact tunable polarized X-ray source based on laser-plasma helical undulators
Ji Luo, Min Chen, Ming Zeng +7
Laser wakefield accelerators have great potential as the basis for next generation compact radiation sources because their accelerating gradients are three orders of magnitude larg…
Enhanced collimated GeV monoenergetic ion acceleration from a shaped foil target irradiated by a circularly polarized laser pulse
M. Chen, A. Pukhov, T. P. Yu +1
Using multi-dimensional particle-in-cell (PIC) simulations we study ion acceleration from a foil irradiated by a circularly polarized laser pulse at 1022W/cm^2 intensity. When the…
