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…
Spin-squeezed vector atomic magnetometry
Jinyang Li, Gour Pati, Renu Tripathi +1
Atomic magnetometers based on Zeeman shift measurement have the potential for high sensitivity and long-term stability. Like other atomic sensors including atomic clocks and atom i…
Spin Squeezing Induced Enhancement of Sensitivity of an Atomic Clock using Coherent Population Trapping
Jinyang Li, Gregório R. M. da Silva, Schuyler Kain +3
The coherent population trapping (CPT) effect is used for making compact atomic clocks. There are two types of CPT clocks: the one in which the Raman beams are applied continuously…
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…
