	Funding: The authors gratefully acknowledge funding supports from National Synchrotron Radiation Research Center, National Tsinghua University, and National Science Council. We study the generation of THz electron pulse trains from a 6 MeV photocathode electron gun driven by a beat-wave laser with a variable beat frequency [1]. We numerically inject the electrons into a single-pass FEL undulator. Owing to the prebunched electron pulse train, the quick shoot-up of the FEL power overcomes the space-charge debunching force in the 6 MeV beam. With nominal beam parameters and an initial bunching factor >5%, the FEL can reach 20-MW saturation power at 6 THz in a half meter long undulator. The length of this 20MW THz FEL, from the beginning of the electron gun to the end of the wiggler, is less than a meter. We will report our experimental progress of this work in the conference.
