Impact of Residual Angular Chirp in a Petawatt-class Laser System on Laser-driven Proton Acceleration
Qingfan Wu, Minjian Wu, Jiarui Zhao +25
The paper shows that a small residual angular chirp caused by misaligned grating compressors in a petawatt laser degrades the focal spot and reduces proton energies, and that remov…

First observation of shock waves induced by laser-accelerated proton beams
Yanlyu Fang, Xiaoyun Le, Yang Yan +5
We demonstrate, for the first time, that laser-accelerated protons can induce shock waves in materials. The ultra-short pulse width of laser-driven protons enables them to deposit…
