DEVICE AND METHOD FOR GENERATING STIMULATED EMISSION OF MICROWAVE OR RADIO FREQUENCY RADIATION

摘要

A device for generating stimulated emission of microwave or radio frequency electromagnetic radiation, the device comprising: a resonator structure;an input source of microwave or radio frequency electromagnetic radiation to be amplified; and an input of energy arranged to pump the resonator structure and thereby cause amplification of the electromagnetic radiation; wherein the configuration of the resonator structure and/or the materials used in its construction give rise to an increase in the magnetic Purcell factor of the resonator structure. Corresponding methods for generating stimulated emission of microwave or radio frequency electromagnetic radiation are also provided.
