Interest in the processes of generation of oscillations in super radiance regimes began with the well-known work by Dicke RN [1]. Super radiance is usually realized in open systems when high-frequency energy is removed from the system. To a certain extent, this energy release can be equivalent to dissipative processes of a distributed type. Previously, dissipative regimes of excitation or generation of an electromagnetic wave in open waveguide resonator systems such as a traveling wave lamp traditionally corresponded to the case of interaction of a waveguide electromagnetic field with radiating particles, most often with moving beam electrons (see example [2]) or scillators. Since the system is open, the field leaves the waveguide, which for short systems is equivalent to losses or dissipative processes of a distributed type. The field damping factor in such a waveguide or resonator without emitters or generators for such generation or amplification modes can be greater than the development increment of the generation process in the presence only these active elements without dissipation or losses [3–5]. In particular, we can consider the case of the interaction of a system of fixed oscillators with the field of an open resonator. In this case, the oscillators did not interact directly with each other, but only through the resonator field common to the system.
