A LASER-PUMPED POTASSIUM MAGNETOMETER FOR GEOPHYSICAL APPLICATIONS

摘要

A new atomic resonance magnetometer for geophysical applications has been developed. This instrument is an optically pumped alkali atom magnetometer, where a diode laser is the pumping optical source. This choice makes possible to use potassium as reference atom, with the advantage of a better control of the instrumental inaccuracy in the measurement on the field.
