Millimeter Wave Imaging using Autler-Townes Splitting Induced Fluorescence from Rydberg Atoms in Rubidium Vapor
Gour Pati, Daniel Mechael, Frederik K. Fatemi +1
We demonstrate millimeter wave (mmWave) imaging using Autler-Townes (AT) splitting-induced fluorescence in rubidium vapor. By employing counter-propagating probe and coupling beams…
Dual-Frequency Absorption Spectroscopy in Laser-Cooled Rubidium Atoms: Theoretical Modeling and Experiment
Gour Pati, Mauricio Pulido, Fredrik K. Fatemi +2
We demonstrate dual-frequency absorption spectroscopy (DFAS) using laser-cooled 87Rb and 85Rb atoms. Doppler-free resonances with high-contrast are produced, which suggest the suit…
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…
