Journal ArticleDOI
Acceleration and evolution of a hollow electron beam in wakefields driven by a Laguerre-Gaussian laser pulse
Guo Bo Zhang,Min Chen,Carl Schroeder,Ji Luo,Ming Zeng,Feiyu Li,Lu-Le Yu,Suming Weng,Yan-Yun Ma,Tong-Pu Yu,Zheng-Ming Sheng,Eric Esarey +11 more
TL;DR: In this paper, a ring-shaped hollow electron beam can be injected and accelerated by using a Laguerre-Gaussian laser pulse and ionization-induced injection in a laser wakefield accelerator.
Journal ArticleDOI
Surface electron acceleration in relativistic laser-solid interactions.
TL;DR: Two-dimensional particle-in-cell simulations show that intense quasistatic magnetic and electric fields are generated near the front target surface during the interaction, and electrons can be accelerated significantly in the reflected laser field, similar to the inverse free-electron-laser acceleration.
Journal ArticleDOI
Propagation of intense laser pulses in strongly magnetized plasmas
X. H. Yang,Wei Dong Yu,H. Xu,M. Y. Yu,M. Y. Yu,Z. Y. Ge,B. B. Xu,Hongbin Zhuo,Yan-Yun Ma,Fu-Qiu Shao,Marco Borghesi +10 more
TL;DR: In this paper, it was shown that a left-hand circularly polarized laser pulse propagating up the density gradient of the plasma along the magnetic field is reflected at the left-cutoff density.
Journal ArticleDOI
Ultrahigh-charge electron beams from laser-irradiated solid surface.
Yong Ma,Yong Ma,J. Zhao,Yifei Li,Dazhang Li,Liming Chen,Jian-Xun Liu,S. J. D. Dann,Yan-Yun Ma,X. H. Yang,Z. Y. Ge,Zheng-Ming Sheng,Zheng-Ming Sheng,Jie Zhang,Jie Zhang +14 more
TL;DR: This work reports the generation of highly collimated electron beams with a divergence angle of a few degrees, nonthermal spectra peaked at the megaelectronvolt level, and extremely high charge via a powerful subpicosecond laser pulse interacting with a solid target in grazing incidence.
Journal ArticleDOI
Generation of high-energy-density ion bunches by ultraintense laser-cone-target interaction
X. H. Yang,Wei Yu,H. Xu,H. B. Zhuo,Yan-Yun Ma,De-Bin Zou,Tong-Pu Yu,Z. Y. Ge,Yan Yin,Fu-Qiu Shao,Marco Borghesi +10 more
TL;DR: In this article, a scheme in which carbon ion bunches are accelerated to a high energy and density by a laser pulse irradiating cone targets is proposed and investigated using particle-in-cell simulations.
