Phase Locking of a Gyrotron Oscillator in the Hard Excitation Mode

In the theory of self-oscillating systems usually one distinguish two different kinds of self-excitation, namely soft and hard excitation. In the soft excitation mode, an unstable noiselevel perturbation grows and evolves into a self-sustained oscillation. Conversely, in the hard excitation mode, a selfoscillation is sustained only for a sufficiently… (More)
