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…
High-efficiency fast pinching radiation of electron beams in nonuniform plasma
Xing-Long Zhu, Min Chen, Zheng-Ming Sheng
The continuous development of bright x/gamma-ray sources has opened up new frontiers of science and advanced applications. Currently, there is still a lack of efficient approaches…
Generation of relativistic polarized electron beams via collective beam-target interactions
Xing-Long Zhu, Min Chen, Wei-Min Wang +1
Relativistic polarized electron beams can find applications in broad areas of fundamental physics. Here, we propose for the first time that electron spin polarization can be realiz…
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…
