Rydberg-atom based radio-frequency electrometry using frequency modulation spectroscopy in room temperature vapor cells
Santosh Kumar, Haoquan Fan, Harald Kübler +2
Rydberg atom-based electrometry enables traceable electric field measurements with high sensitivity over a large frequency range, from gigahertz to terahertz. Such measurements are…
Atom-Based Sensing of Weak Radio Frequency Electric Fields Using Homodyne Readout
Santosh Kumar, Haoquan Fan, Harald Kübler +2
We utilize a homodyne detection technique to achieve a new sensitivity limit for atom-based, absolute radio-frequency electric field sensing of .…
GHz Rabi flopping to Rydberg states in hot atomic vapor cells
B. Huber, T. Baluktsian, M. Schlagmüller +4
We report on the observation of Rabi oscillations to a Rydberg state on a timescale below one nanosecond in thermal rubidium vapor. We use a bandwidth-limited pulsed excitation and…
Electromagnetically Induced Transparency in optically trapped rubidium atoms
Bernd Kaltenhäuser, Harald Kübler, Andreas Chromik +3
We demonstrate electromagnetically induced transparency (EIT) in a sample of rubidium atoms, trapped in an optical dipole trap. Mixing a small amount of -polarized light to th…
