New results of the ‘CLIO’ infrared FEL

This paper shows the new results obtained with the CLIO infrared FEL. The spectral range of the CLIO FEL has recently been extended, and it is now spanning from λ=3–120 μm. We present here some features obtained with CLIO at large wavelengths. We show also measurements of electron energy spectrum after FEL interaction, and we make a comparison with the measured laser power.
