Research on value relation between scanning field and horizontal fleld in optical magnetic resonance experiment

In the experiment of optical magnetic resonance,there are simultaneously pumping signal and resonance signal constantly,which seriously affect the experimental observation and measurement.Based on the influence of the scanning field and horizontal field on the pumping signal,as well as the theoretical analysis and experimental measurement,we find the relationship between the scanning field and the horizontal field,while pumping signal and resonance signal do not exist at the same time.The interference of the pumping signal on the resonance signal and misjudging the direction of the total magnetic field is avoided,so a smooth and accurate experimental measurement is assured.
