Effect of reflection from the remote load on mode competition in a two-mode electronic maser

Effect of reflection from the remote load on the mode competition in a two-mode electronic maser is considered. A system of two coupled equations for slowly varying amplitudes of the modes with time delayed coupling is investigated analytically and numerically. It is shown that the reflections can, under the certain conditions, strongly affect the operation regime. Complicated sequence of transitions from one regime to another which takes place with the increase of reflection factor is investigated.
