An Integrated Atomic Beam Type Optical Frequency Standard

Abstract

The invention discloses an integrated atomic beam type optical frequency marker. The optical frequency standard includes an electrical cabinet and an optical cabinet; the electrical cabinet includes control, measurement and display equipment; the electrical cabinet supplies power to each device in the optical cabinet, and outputs control signals and frequency locking signals to the optical cabinet; the optical cabinet It includes an atomic beam tube, a laser and an ultra-stable laser system; the optical cabinet outputs ultra-stable resonant cavity signals and atomic spectrum signals to the electrical cabinet; the atomic beam tube is an integrated calcium atom beam sealed tube; the laser includes a 423nm Laser and 657nm laser. The design of this optical frequency standard avoids the problems of many lasers and complex systems faced by other optical frequency standard systems, and is expected to become the first commercial time-keeping optical frequency standard that can run continuously. The optical frequency standard of the invention has a clear design principle, is scientific and can be realized by engineering, and is a cutting-edge innovative design in the field of optical frequency standard.

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...
