We apply an innovative strategy to control chaotic diffusion in conservative systems to the case of a single pass Free Electron Laser. The core of our approach is a small apt modification of the system which channels chaos by building barriers to diffusion. By confining the electrons in phase space and limiting the oscillations of the dense core, we aim at stabilizing the laser intensity. Calculations are perfomed within the framework of a simplified Hamiltonian picture. Further extensions and future experimental applications are also discussed.
