Abstract
Apparatus for achieving masing at room temperature, the apparatus comprising: a microwave cavity which exhibits a resonance of sufficiently high Q-factor for maser oscillation; a resonator structure comprising a masing medium located within a resonant element, wherein the masing medium comprises spin-defect centres, the resonator structure being disposed within the microwave cavity; means for applying a magnetic field across the masing medium; an input of microwave radiation to be amplified, the input of microwave radiation being coupled to the resonator structure; and means for optically pumping the masing medium and thereby causing stimulated emission of microwave photons; wherein the microwave cavity has an effective magnetic mode volume matching the volume of the masing medium. A corresponding method for producing masing at room temperature is also provided.
