Abstract
Masers and microwave amplifiers that can function in the continuous-wave mode at room temperature are provided. The maser system can include a diamond gain medium having nitrogen-vacancy centers, and a resonator can be disposed around the gain medium. The resonator can be disposed in a cavity box, and radiation (e.g., visible light) can be provided to the gain medium to cause emission of microwave radiation.
Claims14
A method of providing microwave amplification, the method comprising:
- providing a maser system;
- and
- providing electromagnetic radiation to the maser system, thereby causing the maser system to emit microwave radiation,
- wherein the maser system comprises:
- a gain medium;
- a resonator disposed around the gain medium;
- a cavity box disposed around the resonator;
- and
- a magnet array disposed around the gain medium,
- wherein the gain medium comprises diamond having a plurality of nitrogen-vacancy (NV) centers,
- wherein the electromagnetic radiation is pumped into the cavity box of the maser system at a pump rate that is higher than the decay rate, and
- wherein a cavity Q factor of the maser system is below a masing threshold of the maser system, such that the maser system operates as a microwave amplifier.
