Vector capability is added by effective modulation of the field along orthogonal axes and subsequent demodulation of the magnetic-resonance frequency. This modulation is provided by the AC Stark shift induced by circularly polarized laser beams. The sensor exhibits a demonstrated rms noise floor of 50 fT/Hz^(1/2) in measurement of the field magnitude and 0.5 mrad/Hz^(1/2) in the field direction; elimination of technical nois","authors_text":"B.
