Abstract
A vector magnetometer comprising a cell filled with an atomic gas subjected to an ambient magnetic field, an optical pumping source capable of emitting a pump beam tuned to a pumping wavelength towards the cell and a parametric resonance detection device receiving a probe beam that has passed through the cell, the probe beam being identical to or different from the pump beam. The magnetometer also comprises a polarisation device configured so as to simultaneously or alternately confer linear polarisation and circular polarisation to the pump beam emitted towards the cell. And the detection device comprises an optical set up configured to separate, from the probe beam that has passed through the cell, optical signals carrying respectively information about an alignment state of the atoms from information about an orientation state of the atoms.
