Dead-zone-free single-beam atomic magnetometer based on free-induction-decay of Rb atoms
Shrey Mehta, G. K. Samanta, Raghwinder Singh Grewal
Free-induction-decay (FID) magnetometers have evolved as simple magnetic sensors for sensitive detection of unknown magnetic fields. However, these magnetometers suffer from a fund…
Magnetometry using sodium fluorescence with synchronous modulation of two-photon resonant light fields
Raghwinder Singh Grewal, Mauricio Pulido, Gour Pati +1
We report a new technique for generating magnetic resonance with synchronous modulation of two-photon resonant light fields. Magnetic resonances in fluorescence from a sodium cell…
Light ellipticity and polarization angle dependence of magnetic resonances in rubidium vapor using amplitude-modulated light: Theoretical and experimental investigations
Raghwinder Singh Grewal, Gour Pati, Renu Tripathi
We report on experimental and theoretical investigations of the polarization dependence of magnetic resonance generated by synchronous optical pumping. Magnetic resonances with nar…
Magneto-optical resonances in fluorescence from sodium D2 manifold
Raghwinder S. Grewal, Gour S. Pati, Renu Tripathi +3
We report on magneto-optical resonances observed in sodium fluorescence from D2 manifold with an intensity modulated light. Fluorescence resonances are measured in the perpendicula…
Transient dynamics of nonlinear magneto-optical rotation in the presence of transverse magnetic field
Raghwinder Singh Grewal, Szymon Pustelny
Nonlinear magneto-optical rotation is studied under non-equilibrium conditions. The polarization rotation of linearly polarized light traversing a rubidium vapor cell is observed v…
