Here, we characterize the operating space of a diamond NV-center maser system. Key for the continuous emission of microwave photons is a level inversion, in addition to a high-quality, low mode-volume microwave resonator to enhance the spontaneous emission of the NV-center spin ensemble. We investigate the performance of the maser system as a function of level inversion and resonator quality-factor and construct a phase diagram, identifying the operating parameter space and discuss the optimal working points and pathways for optimization.
