Two methods of efficiency enhancement of free-electron maser (FEM) oscillator with the Bragg resonator having a shift of corrugation phase were studied. The first one is a “starting mode” regime using an additional high-frequency mode located in

It is known that precise frequency tuning of a FEM oscillator with a Bragg resonator could be performed by changing the corrugation phase shift between the reflectors. This report presents new experimental results obtained using a tunable band-pass w

In an FEM oscillator with a Bragg resonator excitation of an additional starting mode can be exploited as a source of an initial signal for the operating mode. In such a regime the starting mode has a rather small detuning from synchronism resulting
