Chirped-Pulse Forward Raman Amplification in Nonuniform Plasmas
Zhi-Yu Lei, Zheng-Ming Sheng, Su-Ming Weng +2
Light amplification via Raman scattering in plasma has been severely constrained by stringent phase matching conditions and the need for plasma uniformity. To overcome these limita…
Acceleration of Ultrahigh Energy Particles from Fast Radio Bursts
Lin Yu, Tianxing Hu, Zhiyu Lei +6
Two extreme events in the universe, fast radio bursts (FRBs) and cosmic rays (CRs), could be correlated, where FRBs with extreme field strength near their sources may contribute to…
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…
