We present preliminary analytical results of enerby extraction and gain of a Free Electron Laser FEL in the presence of a TEMoo Gaussian Mode. Our result is applicable to all values of the paramter q length of the undulator L divided gy the Rayleigh range zRI in second order of the input field. We also present simple analytical approximate expressions for the small single gain valid for q 2.8.
