[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0019] An omnidirectional magneto-optical optical pump magnetometer includes: a light source, a collimation system, an attenuator, a polarization rotator, an atomic gas cell assembly (including an atomic gas cell, two pairs of radio frequency coils), a focusing lens, a photodetector, Signal detection and control circuit.
[0020] The light source 1 is generally a laser light source, such as a semiconductor laser and its temperature control and driving power source. The wavelength corresponds to the working element and energy level of the atomic gas chamber, and should be accurate and stable. Generally, it should have a special frequency stabilization system.
[0021] The collimation system 2 reshapes and collimates the laser light emitted by the light source 1. The ...
