Quantitative spectroscopy of Rb atoms in a strong magnetic field based on submicron thin vapor cell

Influence of Unequal Oscillator Strenghts on Stimulated Raman Adiabatic Passage through Bright State

The problem of the coherent control of atomic states, preparation of atoms in a stable superposition state, and atomic population transfer has attracted much attention in the last decade. One of the main motivations is associated with the rapid development of the field of quantum computing. One of the key problems of quantum information processing is the construction of given coherent superposition atomic states in a macroscopic volume. Stimulated Raman adiabatic passage (STIRAP) [1] is considered to be the most common method for atomic population transfer in quantum systems. Being analyzed in detail on various quantum systems from both theoretical and experimental points of view, this meth…

high contrast sub-natural resonance of increased absorption formed in cell filled with Rb and buffer gas

high-spatial-resolution monitoring of strong magnetic field using Rb nano-thin-cell

Absorption, fluorescence and EIT processes in the extremely thin cell filled with Rb and buffer gas neon

International audience; Comparison of the absorption and fluorescence in the nanocell (or so called extremely thin cell) filled with pure Rb with another one filled with Rb and Neon gas is provided. The effect of the collapse and revival of Dicke-type narrowing is still observable for thickness L=lambda/2, and lambda, where lambda , is a resonant laser wavelength either 780 nm, or 795 nm (for Rb, D2 or D1 line). For L=  so called velocity selective optical pumping (VSOP) resonance located at the atomic transition is still observable, while the linewidth is increased by 4 times in comparison with that obtained in the pure Rb nanocell. Comparison with the theory is presented. Electromagnetic…
