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…
