Investigation of high-intensity laser interaction with gaseous targets and the consequent plasma evolution — •Ralph Jung1, Jens Osterholz1, Oswald Willi1, Marco Borghesi2, Satyabrata Kar2, Lorenzo Romagnani2, Marco Galimberti3, Robert Heathcote4, Carlo Alberto Cecchetti2, and Julien Fuchs5 — 1Heinrich-Heine-Universität Düsseldorf — 2Queens University Belfast — 3IPCF, Consiglio Nazionale delle Ricerche, Pisa — 4CLF, Rutherford Appleton Laboratory, UK — 5École Polytechnique, France
In a recent 100 TW-experiment at the Rutherford Appleton Laboratory (UK) the laser interaction with gaseous targets has been investigated using the proton imaging technique and infrared emission observations. The experiment used the VULCAN pulse (700 fs, 1.05 µm) at focussed intensities of 2-3· 1019 W/cm2. The proton images show evidence of channeled propagation and filamentation of the laser beam, revealed by the associated electric fields.
