Abstract:
Magnetometers based on optically pumped atomic vapors have been known
for half a century. Recently the advent of compact, tunable lasers,
which can replace the discharge lamps of conventional magnetometers, has
renewed the interest in optical magnetometry. They allow one to realize
more sensitive devices and permit to use a single light source for
operating many sensor heads.
I will report on our research in optical magnetometry and discuss two applications of optically pumped magnetometers, viz., the measurement of dynamic field maps generated by the human heart and a new experiment searching for a permanent electric dipole moment of the neutron.
