抄録
内容記述タイプ Abstract
内容記述 We present the experimentally generated electron bunch from laser-wakefield
acceleration (LWFA) with charge of 620 pC and maximum energy up to 0.6 GeV by
irradiating 80 TW laser pulses at 3 mm Helium gas jet. The charge of injected
electrons is much larger than the normal scaling laws of LWFA in bubble regime. We
also got a quasi-mononeregetic electron beam with energy peaked at 249 MeV and
charge of 68 pC with the similar laser conditions but lower plasma density. As
confirmed by 2D particle-in-cell (PIC) simulations, the boosted bunch charge is due
to the continuous injection caused by the self-steepening and self-compression of
laser pulse. During the nonlinear evolution of laser pulse, the bubble structure
broadens and stretches, leading to a longer dephasing length and larger beam charge.
