We report the first direct temporal observation [1] of self-injected and shock-front injected [2] laser-driven electron acceleration. The dynamics of the plasma wave and an electron bunch duration of 6 fs is obtained.
Die Elektronenbeschleunigung mit Lasern könnte schon bald die klassische Beschleunigungstechnik revolutionieren. Um diese Technik nutzen zu können, ist jedoch ein genaues Verständnis der hierbei auftretenden, komplexen Vorgänge notwendig. Wissenschaftlern des Max‐Planck‐Instituts für Quantenoptik, der Ludwigs‐Maximilians‐Universität München und der Friedrich‐Schiller‐Universität Jena ist es kürzlich...
A plasma mirror is shown to enhance the intensity contrast of 8fs multiterawatt light pulses by 2.5 orders of magnitude, while keeping the pulse duration unchanged. High reflectivity and improved near-field beam quality are demonstrated.
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...
