The capabilities of two types of terahertz sources based on stimulated Smith – Purcell radiation of electrons in open cavities are discussed. A series of developed pulsed orotrons provides coherent radiation at frequencies up to 410 GHz with an output power of 1–0.1 W with high frequency stability. A promising alternative source with smaller currents than in orotrons is a frequency multiplier based on the excitation of a surface wave of a periodic structure and Smith – Purcell radiation of arising electron bunches inside the orotron cavity. A possibility of frequency doubling inside the orotron cavity is experimentally demonstrated at a frequency of 190 GHz.
