摘要：

A compact Cherenkov free-electron laser operating in the terahertz spectral range is being developed. Analysis of the double-slab type optical resonator has clarified the resonant frequency, the small signal gain, and the saturation power of the device. One-dimensional simulation code predicted a small signal gain of 6% with a 50 kV/3.6 mA electron beam. The saturation power was estimated to be 90 mW. The out-coupling structure of the resonator was designed using 3D simulation code. A transmittivity of 3.0% and a spread angle of 0.4 rad were predicted.
