摘要：

A quasi-optical gyrotron (QOG) designed for operation at the fundamental (fce≃100 GHz) exhibits simultaneous emission fce and 2fce (second harmonic). For a beam current of 4 A, 20% of the total rf power is emitted at the second harmonic. The experimental measurements show that the excitation of the second harmonic is only possible when the fundamental is present. The frequency of the second harmonic is locked by the frequency of the fundamental. Experimental evidence shows that when the second harmonic is not excited, total efficiency is enhanced. © 1990 American Institute of Physics.
