Abstract

The invention discloses an integrated head device of an SERF atom magnetometer. For the optical excitation detection and high-temperature heating requirements required by a gas chamber of a head of the SERF atom magnetometer, integrated design is carried out on key components, such as an excitation component, a detection component, a heating component and a heat insulation component; excitation light and detection light enter in parallel through an adjustable mirror structure to greatly reduce the volume of the head; and components around an alkali metal gas chamber are fixed by using a tightfit structure, so that the volume of the head of the SERF atom magnetometer is reduced, the debugging efficiency of an excitation device and a detection device is improved, and meanwhile, heat conduction of a heating device and an external environment is reduced. The head device with high reliability and high stability is provided for miniaturization of an SERF atom magnetometer array and measurement study of SERF magnetic fields.

Description

technical field [0001] The invention belongs to the field of atomic magnetometers, and in particular relates to an integrated head device of a SERF (Spin-Exchange-Relaxation-Free, no spin exchange relaxation) magnetometer. Background technique [0002] The ultra-high sensitivity and extremely weak magnetic measurement device based on the SERF atomic spin effect has achieved better than 0.1fT / Hz 1 / 2 The magnetic field measurement sensitivity is towards aT(10 -18 T) magnitude development. Ultra-high sensitivity and extremely weak magnetic field measurement has great application prospects in the fields of metrology standards, brain science and medicine, and material science. However, the polar magnetic field measurement device with the highest measurement sensitivity is still in the stage of experimental research platform, and there is an urgent need for miniaturized SERF magnetic field. To promote its rapid development in related fields. The SERF magnetometer head device is...
