摘要：

We report on laser-driven electron acceleration with 8 fs, i.e. three optical cycles, pulse duration and 40 mJ energy. Theory and numerical simulations predict that this experimentally unexplored parameter range is relevant for laser wake-field acceleration. The electron spectra produced are monoenergetic with a peak up to 50 MeV and free of low-energy electrons with thermal spectrum. The electron beam has a typical divergence of 5-10 mrad. The accelerator is routinely operated at 10 Hz and correspondingly it is a promising source for several applications. To cite this article: L. Veisz et al., C R. Physique 10 (2009).
