Rydberg-atom based radio-frequency electrometry using frequency modulation spectroscopy in room temperature vapor cells.
Rydberg atom-based electrometry enables traceable electric field measurements with high sensitivity over a large frequency range, from gigahertz to terahertz. Such measurements are particularlyExpand

Effect of Vapor-Cell Geometry on Rydberg-Atom-Based Measurements of Radio-Frequency Electric Fields
A new approach to detect absolute radio-frequency (rf) electric fields (E-fields) that uses Rydberg atoms at room temperature in vapor cells has been demonstrated recently. The large-transitionExpand

Subwavelength microwave electric-field imaging using Rydberg atoms inside atomic vapor cells.
We have recently shown [Nat. Phys.8, 819 (2012)] that Alkali atoms contained in a vapor cell can serve as a highly accurate standard for microwave (MW) electric field strength as well asExpand

Atom-Based Sensing of Weak Radio Frequency Electric Fields Using Homodyne Readout
We utilize a homodyne detection technique to achieve a new sensitivity limit for atom-based, absolute radio-frequency electric field sensing of 5 μV cm−1 Hz−1/2. A Mach-Zehnder interferometer is usedExpand

Atom-based RF electric field measurements: An initial investigation of the measurement uncertainties
We discuss a new method for the measurement of electric (E) fields that will lead to a self-calibrating, direct SI-traceable E-field probe. The technique is based on radio frequency E-fieldExpand

Dispersive radio frequency electrometry using Rydberg atoms in a prism-shaped atomic vapor cell
We introduce a method to measure radio frequency (RF) electric fields (E-fields) using atoms contained in a prism-shaped vapor cell. The method utilizes the concept of electromagnetically inducedExpand

Intracavity Rydberg-atom electromagnetically induced transparency using a high-finesse optical cavity
We present an experimental study of cavity assisted Rydberg atom electromagnetically induced transparency (EIT) using a high-finesse optical cavity ($F \sim 28000$). Rydberg atoms are excited via aExpand

Cavity dispersion tuning spectroscopy of tellurium near 4444 nm
We present saturation absorption spectroscopy of transitions in Te2 near 444.4 nm. These spectra were taken using a blue diode laser locked to a Fabry–Perot (FP) cavity that is in turn locked to aExpand
