Abstract

The invention relates to the technical field of optical pumping, and in particular to an axial magnetic field adjustment device and a corresponding adjustment method which can be used for an optical pumping device. The device comprises an optical pumping generation assembly S1, a magnetic field intensity and position detection assembly S2, a magnetic field position adjustment assembly S3 and a magnetic field generation control assembly S4. According to the device and method, magnetic field intensity and position control is carried out by employing vector superposition of a magnetic field, relatively high sensitivity is achieved, no extra residual magnetic field is introduced, the axial magnetic field adjustment device is simple in structure and relatively small is size, and magnetic field adjustment inside a magnetic shielding barrel can be achieved.

Description

Technical field [0001] The present invention relates to the field of optical pumping technology, in particular to an axial magnetic field adjustment device that can be used in an optical pumping device and a corresponding adjustment method. Background technique [0002] Optical pumping is a kind of technology that uses laser to irradiate a working substance to cause the particle number in the substance to be reversed, and finally make most of the atoms in a specific state of the same energy level, that is, to achieve atomic polarization. In the fields of timing, magnetometer, quantum optics, navigation and medicine, optical pumping has been widely used. [0003] The basic principle of optical pumping is to transfer the angular momentum of photons to atoms through the interaction of lasers and atoms. In a broad sense, optical pumping realizes the arrangement of the degrees of freedom of atomic translation and spin. A typical optical pumping experiment structure includes the follow...
