Maser Threshold Characterization by Resonator Q-Factor Tuning
| Description | The previous demonstration of a maser based on NV- centers in diamond has been reproduced with a different diamond using a new microwave resonator with an iris rather than an antenna for coupling out the microwaves. Furthermore, we have shown that the output of the maser may be controlled by the Quality factor of the resonator. |
| Exploitation Route | This work lays the groundwork for achieving masing with diamond & silicon carbide. |

| Title | ROOM TEMPERATURE MASING USING SPIN-DEFECT CENTRES |
| Description | 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. |
