An economical, coherent, and widely tunable source does not exist spanning the far-infrared electromagnetic spectral range of 50-1000 {mu}m in wavelength. The Cerenkov free-electron laser (CFEL) is a promising candidate. This report describes an experimental investigation of a compact CFEL driven by a high-quality low-energy electron beam. Cerenkov emission and strong gain but remarkably low output coupling were observed.
