Abstract
Optical resonator plays a crucial role in the oscillator scheme of Free Electron Laser (FEL). In this paper, the challenges and some issues on the optical configurations for FEL resonators are presented. Firstly, the diffraction loss and power density are calculated during the preliminary parameters design. Then the detuning and alignment issues of the cavity are discussed with theoretical and numerical simulations. To minimize the influence of the harmonics components, the potential solution based on their spatial distributions is also provided.
