Description

Laser wakefield acceleration can sustain accelerating gradients three orders of magnitude higher than conventional radio-frequency accelerators, making it a crucial piece of the puzzle for realizing compact particle accelerators and radiation sources. Many international teams have been devoting themselves to this promising yet highly challenging frontier. This talk presents a decade-long experiment[1-4]. A research team from the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has systematically overcome multiple experimental and engineering obstacles, progressively improving beam quality and stability. The culmination of this sustained effort is the world's first demonstration of free-electron lasing driven by a laser wakefield accelerator[5]. This breakthrough would not have been possible without the close collaboration and persistent dedication of scientists working in both laser and plasma physics. Yet, this achievement represents only "a snapshot" of the global efforts aimed at breaking through in this research direction — researchers from many countries continue to strive for making laser wakefield accelerators a true practical reality[6-9]. In the future, we all hope to advance this field further through broader international cooperation and exchange[10].
