	Recently, at the Laboratoire d'Optique Appliquée, progresses have been made for the development of 5th generation light sources based on plasma-accelerator. Electron beams of tens of picocoulomb at about 200 MeV has been generated at the interaction of a 1 Joule, 30 fs laser focussed on a 3 mm long gas target at an electron density of 5 10¹⁸ cm^-3. Then, the electron beam was refocused with a quadrupoles triplet inside a 60 cm long undulator composed of 34 periods of 18 mm with a deflection parameter equal to 1. In these conditions synchrotron radiation UV light has been measured. This constitutes a promising first step in the view of realizing FEL based on plasma acceleration in future.
