Abstract

Recently, at the Laboratoire d'Optique Appliquée (LOA), progresses have been made for the development of 5th generation light sources based on laser-plasma-accelerator. Electron beam from 100 to 150 MeV was generated at the interaction of a 1 Joule, 30 fs laser focused on a 3 mm long He gas target at an electron density of about 5*1018 cm-3. Then, the electron beam was focused with a quadrupoles triplet inside a 60 cm long undulator composed of 34 periods of 18 mm. In these conditions, synchrotron radiation light was measured from 450 nm to 230 nm. This constitutes a promising first step in the view of realizing FEL based on plasma acceleration in future.
