The Research of Optical Pumping Magnetic Resonance Experiment
Abstract: The optical pumping magnetic resonance experiment is putting the experimental samples under the action by the optical frequency and radio-frequency electromagnetic field together and making them resonate. We detect the radiation or absorption about the optical quanta of the samples not about the radio-frequency quanta, when detecting the magnetic resonance. This is just the way of detection with light. This method not only keeps the high-definition but also improves the degree of sensitivity when detecting the signal, for the energy of the optical quanta is higher 7-8 orders of magnitude than that of radio-frequency quanta. In the paper, with optical pumping magnetic resonance instrument, firstly, the value of the landẻ g-favtor and the magnitude of the earth magnetic is measured; secondly, the optical pumping magnetic resonance instrument is changed into the weak magnetic signal measurement device, the range of its measurement is tested; finally, the line breadth of the resonance signal is measured.
