Experimental results are presented of the first cyclotron autoresonance maser oscillator operated using the second harmonic of the cyclotron frequency. An interaction efficiency of 3.9{percent} has been measured at a frequency of 14.27 GHz, using an 80 ns pulsed, 14 A electron beam of energy 300 keV, to produce a coherent microwave power of 170 kW. Emission occurred at 3.7 times the relativistic cyclotron frequency, due to the large Doppler frequency increase and second harmonic interaction. {copyright} {ital 1996 The American Physical Society.}
