TL;DR: In this article, the authors achieved a new power record of 62 kW at approximately 388 GHz with second-harmonic (SH) oscillation and modified the electron gun of the gyrotron to couple the electron beam more strongly to another oscillation mode that has a peak coupling coefficient two times as large as that of the 62 kW mode.
