Abstract
A magnetometer is desclosed in which a gas cell containing atomic vapor is pulse pumped at one of the transitions of the gas in the cell. After the pulse has passed through the gas cell, thereby causing alignment of all the individual atomic moments along the propagation direction of the pulse, a probe beam reads out the Larmor precession frequency of the freely precessing atoms in terms of the frequency of the amplitude modulation of the probe beam caused by the free precession within the gas cell. The system is suitable for laboratory measurements of the absolute value of a magnetic field and for packaging in an expendable battery powered water-born buoy becuase of the low power consumption of the subject system.
