Atomic beams are a longstanding technology for atom-based sensors and clocks with
widespread use in commercial frequency standards. Here, we report the demonstration of a …

We report on the mid-term stability progress of a table-top coherent population trapping
(CPT) microcell atomic clock, previously limited by light-shift effects and variations of the …

We demonstrate and study a microcell microwave atomic clock based on optical-microwave
double resonance (DR) interrogation operated in a pulsed Ramsey scheme, called the μ …

The mid-term fractional frequency stability of miniaturized atomic clocks can be limited by
light-shift effects. In this Letter, we demonstrate the implementation of a symmetric auto …

We investigate the application of Ramsey spectroscopy for the development of a microcell
atomic clock based on coherent population trapping (CPT). The dependence of the central …

To reliably register the absorption or selective reflection of laser radiation in a nanocell filled
with a vapor of Cesium or Rubidium at thicknesses below 100 nm, it becomes necessary to …

The increased spectral resolution allowed by the use of extremely thin vapor cells has led to
the observation of interesting behavior of alkali transitions when placed in a magnetic field …

Atomic transitions satisfying F e− F g= Δ F=±2 (where F e stands for excited and F g stands
for ground state) of alkali atoms have zero probability in zero magnetic field (they are so …

In this study, a dual-interrogation (DI) method was used to suppress the light shift in the Rb
778 nm 5S_1/2→ 5D_5/2 two-photon transition optical frequency standard (2hν-OFS). The …

We report on the operation of a coherent population trapping (CPT) microcell atomic clock
using a pulsed Ramsey-like interrogation. The Ramsey-CPT sequence, defined by two-step …
