Impact of Residual Angular Chirp in a Petawatt-class Laser System on Laser-driven Proton Acceleration
Qingfan Wu, Minjian Wu, Jiarui Zhao +25
Laser-driven proton acceleration has attracted considerable interest owing to its appealing potential in versatile applications including cancer therapy. Proton energies depend cri…
HotLoop Optimization of Petawatt Laser Focal Spot via a Twin-Focus Scheme
Qingfan Wu, Ying Gao, Minjian Wu +25
Achieving diffraction-limited focusing of high-power laser pulses to generate ultra-high intensities is crucial for developing compact laser-driven particle accelerators and explor…
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…
Ultra-short lifetime isomer studies from photonuclear reactions using laser-driven ultra-intense γ-ray
Di Wu, Haoyang Lan, Jiaxing Liu +29
Isomers, ubiquitous populations of relatively long-lived nuclear excited states, play a crucial role in nuclear physics. However, isomers with half-life times of several seconds or…
