Within the framework of the cubic nonlinear approximation, the theory of the interaction of multiharmonic waves of the HPZ in the amplification section of a superheterodyne LVE with a longitudinal electrostatic undulator is constructed. Multiharmonicity of the pump field is taken into account. Within the framework of the nonlinear cubic approximation, the control of the width of the frequency spectrum in multiharmonic two-stream lasers on free electrons of the klystron type with the help of a longitudinal electric field was analyzed.
