摘要
We demonstrate an optically pumped Rb-87 magnetometer in a microfabricated vapor cell based on a zero-field dispersive resonance generated by optical modulation of the Rb-87 ground state energy levels. The magnetometer is operated in the spin-exchange relaxation-free regime where high magnetic field sensitivities can be achieved. This device can be useful in applications requiring array-based magnetometers where radio frequency magnetic fields can induce cross-talk among adjacent sensors or affect the source of the magnetic field being measured.
