Multistability of Phase-Locked Modes in a System of Two Delay-Coupled Gyrotron Oscillators

THz range gyrotrons operating in continuous mode are of great interest for many applications, such as spectroscopy, plasma diagnostics, biomedical research, etc. These applications require high frequency stability. In addition to the existing methods of spectrum generation control, the use of various types of synchronization has recently attracted interest. In particular, mutual synchronization of two coupled gyrotrons, which is presented in this article. The mechanism of transition to synchronization at the desired frequency is considered.
