Abstract: In the experiment of optical magnetic resonance, there are simultaneously pumping signal and reso- nance signal constantly, which seriously affect the experimental observation and measurement. Based on the influ- ence of the scanning field and horizontal field on the pumping signal, as well as the theoretical analysis and experi- mental 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.
