| 摘 要： | 在光磁共振实验中,常常有抽运信号与共振信号同时存在的情况,这严重影响到实验的观察和测量.本文利用扫场及水平场大小对抽运信号的影响,通过理论分析和实验测量得到抽运和共振信号不同时存在时扫场和水平场的取值关系.从而有效避免抽运信号对共振信号的干扰,以及对总磁场方向误判的情况,保证了实验的顺利进行和准确测量.

| Abstract: | 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. |
