Microwave induction method and device based on Rydberg atoms

Abstract

The invention relates to a microwave detection technology, particularly relates to a microwave induction method and device based on Rydberg atoms, and solves the technical problems that current equipment for microwave field detection easily disturbs a microwave field. The microwave induction method based on the Rydberg atoms comprises the following steps: (a) after combining two beams of laser and expanding the combined beams, and emitting the laser into a transparent sample tank filled with alkaline metal atom steam; (b) filtering laser which is emitted out from the sample tank and has the frequency the same as that of a second laser beam, acquiring residual laser signals and converting the laser signals into corresponding electric signals; and (c) if the microwave field exists at the position of the sample tank and signals with the reduced strength of the first beam of the laser are acquired, judging that the microwave field exists at the position of the sample tank. According to the microwave induction method and device based on the Rydberg atoms, the problems of an existing microwave induction technology that the volume is large and the detection sensitivity is low are solved. With the adoption of the microwave inductor based on the Rydberg atoms, whether the microwave field exists in the environment or not can be measured rapidly and accurately.

Description

technical field [0001] The invention relates to microwave detection technology, in particular to a microwave induction method and device based on Rydberg atoms. Background technique [0002] The prior art mainly refers to the standard antenna and standard field method when measuring the microwave electric field. For existing microwave detection instruments, the main limitation is the antenna, because it needs to convert the microwave electric field into some observable quantities, such as voltage, which also depends on the geometry of the antenna, which will cause interference to the microwave electric field, It leads to inaccurate measurement results and low sensitivity. Moreover, the currently commonly used microwave field detection devices are bulky and inconvenient to use and carry. Therefore, there is a need for a microwave detection method and device that does not interfere with the microwave electric field, has high sensitivity, and is small in size. Contents of t...
