A crucial step toward enabling real-world applications for quantum sensing devices such as
Rydberg atom electric field sensors is reducing their size, weight, power, and cost (SWaP-C) …

We present measurements of the cross-correlation function of photon pairs at 780 and 1367
nm, generated in a hot rubidium vapor cell. The temporal character of the biphoton is …

An excited-state Faraday anomalous dispersion optical filter (ESFADOF) operating on the
rubidium 5P 3/2-4D 5/2 transition (1529.4 nm in vacuum) is demonstrated, which utilizes an …

We demonstrate a technique to lock simultaneously two laser frequencies to each step of a
two-photon transition in the presence of a magnetic field sufficiently large to gain access to …

In this paper, we present the development and testing of a balanced Zeeman spectroscopy
method utilizing wavelength modulation for selective detection of paramagnetic molecules …

We present a laser frequency locking to Rydberg transition with electromagnetically induced
transparency (EIT) spectra in a room-temperature cesium vapor cell. Cesium levels 6S 1/2 …

The performance of laser-based instruments heavily depends on the stability of their laser
source. Some instruments, such as the Cs–4 He magnetometer, even require the frequency …

In this work, we have applied polarization spectroscopy to study electromagnetically induced
transparency involving hot Rb 85 Rydberg state in a vapor cell using a Laguerre–Gaussian …

We propose a method to continuously frequency shift a target laser that is frequency
stabilized by a reference laser, which is several hundreds of nanometers detuned. We …

We demonstrate modulation-free laser stabilization to an atomic Rydberg transition using
nonlinear polarization spectroscopy. To stabilize a laser to the upper transition of a three …
