The dynamic Stark effect is considered for the case when Stark splittings exceed the hyperfine intervals. The electromagnetic field is supposed to be monochromatic and the quasi-energy approach is applied. The HFS of the quasi-energy levels is shown to be dependent on the intensity of the resonance electromagnetic field and on the detuning. The resonance fluorescence and absorption spectra of a probe field are calculated based on the density matrix method. The Ag atom is taken as an example.

In the Λ three-level system, we will make use of semi-classical density matrix method to analyze cesium (Cs) hyperfine structure of coherent population trapping (CPT) phenomenon. Coherent population trapping has been widely used in electromagnetically induced transparency, non-inversion laser, optical storage and ultra-slow speed of light fields, then strong-coupling light and weak detecting light form coherent laser light to change the hyperfine structure energy levels of particles number distribution, which impacts on laser pumping magnetic resonance. In this paper, we will discuss the theoretical analysis and system design of laser pumping cesium magnetometer, cesium atomic energy level formed hyperfine structure with the I-J coupling, the hyperfine structure has been further split into Zeeman sublevels for the effects of magnetic field. To use laser pump and RF magnetic field make electrons transition in the Zeeman sublevels to produce the results of magneto-optical double resonance and on this basis we analyze the influence of laser pumping magnetic resonance based on coherent population trapping.
