Abstract

We show that phase- and frequency-locking of a gyrotron with very-high-order operating mode TE56.24 by a relatively weak external monochromatic signal allows for MW-level power, high efficiency and high frequency- and phasestability of radiation in the terahertz frequencies region and broadens frequency tuning bandwith. Thus, significant enhancement of radiation parameters can be achieved. Such gyrotrons may be used in large complexes of coherently radiating gyrotrons for THz data and energy transmission and applied for electron cyclotron resonance heating and current drive (ECRH and CD) systems and for THz particles acceleration. We also show possibility of parametric 4-wave decay at the exit from the locking mode.
