Abstract
At the Institute of Laser Engineering, various type of experiments related to fast ignition were performed with the 12-beam laser system GEKKO XII and the newly added 100 TW beams line. Using both X-ray and UV laser probes, d rilling via ponderomotive laser light self-focusing was studied to show dri lling well into the overdense plasma over a distance of 100 mum at a self-f ocused laser intensity of 10(18) W/cm(2). This type of self-focusing accele rated electrons up to 0.1 to 1 MeV and was also applied to an imploding she ll. (C) 2000 Academie des sciences/Editions scientifiques et medicales Else vier SAS.
