ABSTRACT:
Free electrons laser with gaseous medium wiggler and method to use this laser. The laser includes a chamber (22) designed to be traversed by a beam of previously accelerated electrons, a wiggler (44) which creates in this chamber a periodic magnetic field interacting with the beam of electrons, and means (54) to fill the chamber with a gas formed of atoms or molecules having at least one resonance line at a determined frequency. The laser is tuned on this resonance line, which enables the laser to produce a frequency light close to this determined frequency.
