SUMMARY
Gyrotrons are the most powerful sources of coherent radiation based on cyclotron excitation of the high-Q near-cutoff mode of open cavities by a beam of electrons rotating in the strong axial magnetic_fields. Since the frequency of a traditional fundamentalcyclotron-harmonic gyrotron is close to the electron cyclotron frequency, the advancement of such devices to the terahertz frequencies is limited by the attainable magnetic_fields. In recent years, subterahertz gyrotrons operating at 2nd and 3rd harmonics of gyro-frequency have been demonstrated to extend the gyrotron frequency range otherwise limited by the maximum value . . .
