Journal ArticleDOI
Enhancement of electron energy to the multi-GeV regime by a dual-stage laser-wakefield accelerator pumped by petawatt laser pulses.

TL;DR: A significant increase in laser-driven electron energy to the multi-GeV level by utilizing a 30-fs, 1-PW laser system and a dual-stage laser-wakefield acceleration scheme was applied to boost electron energies to over 3 GeV with a single PW laser pulse.
Journal ArticleDOI
Stable generation of GeV-class electron beams from self-guided laser–plasma channels

TL;DR: In this paper, stable GeV-class electron beams were generated from stable few-millimetre-long plasma channels in a self-guided wakefield acceleration process. But the stability of beam generation and the ability to scale to higher electron beam energies are critical issues for practical laser acceleration.
Journal ArticleDOI
4.2 PW, 20 fs Ti:sapphire laser at 0.1 Hz
Jae Hee Sung,Hwang Woon Lee,Je Yoon Yoo,Jin Woo Yoon,Chang Won Lee,Jeong Moon Yang,Yeon Joo Son,Yong Ha Jang,Seong Ku Lee,Chang Hee Nam +9 more
TL;DR: The generation of 4.2 PW laser pulses at 0.1 Hz from a chirped-pulse amplification Ti:sapphire laser will be a workhorse for exploring high field science.
Journal ArticleDOI
Laser-driven proton acceleration enhancement by nanostructured foils.

TL;DR: Nanostructured thin plastic foils have been used to enhance the mechanism of laser-driven proton beam acceleration, leading to a consequent increase in the maximum proton energy and beam charge and to the first experimental demonstration of such advanced target geometry.
Journal ArticleDOI
Generation of high-contrast, 30 fs, 1.5 PW laser pulses from chirped-pulse amplification Ti:sapphire laser.
TL;DR: A high-contrast, 30 fs, 1.5 PW Ti:sapphire laser has been developed for research on high field physics and an adaptive optics system was implemented for obtaining the near diffraction-limited focal spot.
