Abstract:	摘要： We visualize ps-time-scale evolution of an electron density bubble--a wake structure created in atmospheric density plasma by an intense ultrashort laser pulse--from the phase "streak" that the bubble imprints onto a probe pulse that crosses its path obliquely. Phase streaks, recovered in one shot using frequency-domain interferometric techniques, reveal the formation, propagation, and coalescence of the bubble within a 3 mm long ionized helium gas target. 3D particle-in-cell simulations validate the observed density-dependent bubble evolution, and correlate it with the generation of a quasimonoenergetic ∼ 100 MeV electron beam. The results provide a basis for understanding optimized electron acceleration at a plasma density n(e) ≈ 2 × 10(19) cm(-3), inefficient acceleration at lower density, and dephasing limits at higher density. 其他題名： Phys Rev Lett 出版者： United States: American Physical Society (APS) 出版日期： 2014-08-22 出處： Physical Review Letters, 2014-08, Vol.113 (8), p.085001, Article 085001 資源來源： American Physical Society Journals 識別號： ISSN: 0031-9007 識別號： ISSN: 1079-7114 識別號： ISSN: 1092-0145 識別號： EISSN: 1079-7114 識別號： DOI: 10.1103/physrevlett.113.085001 識別號： PMID: 25192102
