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.
