Radiation of a flow of oscillating electrons in the excitation of parametric oscillations

A study is made of phase modulation of an electron flow and the saturation of coherent radiation in such a flow after parametric excitation in a nonlinear system. Expressions are obtained for the intensity of the radiation of a charged particle and the coherent radiation in a resonator. The dependece of the intensity and frequency of the radiation on the amplitude and frequency of the external source are examined.
