Abstract
A solution has been proposed about ten years ago to reach the X-ray range: the principle is to operate the FEL in the Self-Amplified Spontaneous Emission (SASE) configuration. In the high gain regime, the spontaneous emission is amplified along the undulator in a single pass configuration and without optical cavity. We report here the observation of SASE at the shortest wavelength, the mid-infrared range. A spectral analysis of the SASE has been carried-out in the start-up regime of SASE, far from the saturation level.
