Method and the system in order to move the atomic clock with alternate polarized light light

摘要

This invention the coherent population trapping which is used by exciting the atom with light of the alternate polarized light, in the atomic clock and the magnetometer (CPT) strength of resonance offers the method and the device in order to increase. Excitation with that kind of light which is characterized by the photon spin vector where direction alternates at super minute frequency of the atom at the time of arranging the atom is named the push pull pumping. In one execution form of the system of this invention, the CPT resonance which at suitable resonance frequency strength the alkaline metallic vapor can be excited with the alternate rotary polarized light D1 laser beam which is modulated be observed with that, as increase of average transmissivity of the alkaline metallic vapor, is generated. These resonance are strengthened originating in the centralization to the resonance energy sub-lebel of the atom which is pulled up optically, substantially.
