Towards the Generation of Petawatt Near-Infrared Few-Cycle Light Pulses via Forward Raman Amplification in Plasma

Author(s): Zhi-Yu Lei, Zheng-Ming Sheng, Su-Ming Weng, Min Chen, and Jie Zhang Light amplification toward 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 amplify a laser pulse with tunable wavelengths toward extremely high power via forward Raman amplification in plasma. Differe… [Phys. Rev.
