title: Transient solutions to a three level maser.
abstract: The transient behavior of three-level paramagnetic masers is investigated theoretically. Exact solutions to three-level maser rate equations are developed and their significance discussed. The results indicate the possibility of obtaining enhanced maser action at low saturation by pulsed pumping. A new method for the measurement of spin-lattice relaxation times for a three-level maser is proposed. The method, in addition to certain well-known static measurements, requires the observation of the decay of the signal strength when the pumping field is switched off.
