Abstract :
An exact analysis of the gain function of the cavity maser is made and is presented in graphical form suitable for correlation with experiment. Combined with measurements of the reflection coefficient of the passive cavity, and gain and bandwidth of the maser, the results yield accurate values for the unloaded, external and magnetic Q-factors of the cavity maser. The analysis also applies to any other resonant one-port device, e.g. a parametric amplifier.
