Doppler-free Selective Reflection spectroscopy of the $6 s$ $^{2} S_{1/2} \to 7 p$ $^{2} P_{3/2}$ transition of Cesium using a nanofabricated vapor cell

Armen Sargsyan, Rodolphe Momier, David Sarkisyan

Selective Reflection (SR) spectroscopy of the $6 s$ $^{2} S_{1/2} \to$ $7 p$ $^{2} P_{3/2}$ electric dipole transition of Cesium ( $λ = 456$ nm) is performed for the first time usin…

Sub-Doppler spectra of sodium $D$ lines in a wide range of magnetic field: theoretical study

Rodolphe Momier, Aram V. Papoyan, Claude Leroy

We compute the interaction of a sodium vapor with a static magnetic field ranging from 0 up to 1 Tesla, which allows to obtain the behavior of all Zeeman transitions as a function…

New standard magnetic field values determined by cancellations of $^{85} Rb$ and $^{87} Rb$ atomic vapors $5^{2} S_{1/2} \to 6^{2} P_{1/2, 3/2}$ transitions

Rodolphe Momier, Artur Aleksanyan, Emil Gazazyan +2

In this article, we study the theoretical behaviour of all the possible hyperfine transitions ( $π$ , $σ^{+}$ and $σ^{-}$ ) between the $5 S$ and $6 P$ states of $^{87} Rb$ and ${}^…

Transition cancellations of $^{87}$ Rb and $^{85}$ Rb atoms in a magnetic field setting new standards

Artur Aleksanyan, Rodolphe Momier, Emil Gazazyan +2

We have analyzed the magnetic field dependences of intensities of all the optical transitions between magnetic sublevels of hyperfine levels, excited with $σ^{+}$ , $π$ and $σ^{-}$ pola…
