Integrated atom beam type optical frequency standard

Abstract

The invention discloses an integrated atom beam type optical frequency standard comprising an electrical cabinet and an optical cabinet. The electrical cabinet consisting of a control device, a measurement device, and a display device provides power for all devices of the optical cabinet and outputs a control signal and a frequency locking signal to the optical cabinet. The optical cabinet including an atomic beam tube, a laser device and an ultra-stable laser system outputs an ultra-stable resonant cavity signal and an atomic spectrum signal to the electrical cabinet; the atomic beam tube isan integrated calcium atom beam sealing tube; and the laser device includes a 423-nm laser device and a 657-nm laser device. On the basis of the optical frequency standard design, problems of many laser devices and complicated system of other optical frequency standard systems are solved; and the provided optical frequency standard is expected to be a first commercial time-keeping optical frequency standard capable of working continuously. The optical frequency standard based on the clear design principle has the high scientificity and engineering achievablility and a leading-edge novel designin the optical frequency standard field is provided.

Description

technical field [0001] The invention relates to the technical field of atomic frequency standards. More specifically, it relates to an integrated atomic beam type optical frequency standard. Background technique [0002] In the field of atomic frequency standards research, the main research objects are microwave atomic frequency standards and optical frequency standards. At present, microwave atomic clocks are commercialized, including hydrogen clocks, rubidium clocks, cesium beam clocks, and cesium fountain clocks. These atomic clocks are mature products, but the core stability indicators lack room for improvement. With the development of laser technology and laser cooling technology, scientists have carried out research on optical frequency standards, and quickly surpassed microwave atomic frequency standards in terms of indicators, becoming the most cutting-edge research direction in the field of atomic frequency standards. In recent years, optical frequency standard t...
