| 英文摘要 | We present the experimentally generated electron bunch from laser-wakefield acceleration (lwfa) with a charge of 620 pc and a maximum energy up to 0.6 gev by irradiating 80 tw laser pulses at a 3mm 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-monoenergetic electron beam with energy peaked at 249mev and a charge of 68 pc with the similar laser conditions but lower plasma density. as confirmed by 2d particle-in-cell simulations, the boosted bunch charge is due to the continuous injection caused by the self-steepening and self-compression of a laser pulse. during the nonlinear evolution of the laser pulse, the bubble structure broadens and stretches, leading to a longer dephasing length and larger beam charge. published by aip publishing. |
