Zusammenfassung:The time variation of amplitude of a maser oscillator is derived from a study of the rate equations connecting the population inversion and the electromagnetic energy stored in the maser resonator. The methods of nonlinear mechanics are used to derive a qualitative description of the amplitude variation in the absence of a complete solution of the rate equations. Modifications of the simple rate equations necessary to account for the existence of undamped relaxation oscillations are introduced for both microwave and optical masers, and their physical significance is discussed. The production of 'giant pulses' of radiation is also treated. (Author) Report on Proj. Michigan.
