We present high resolution laser spectroscopy of Cs vapours confined in a unique optical cell of sub-micrometric and micrometric thickness, where a strong spatial anisotropy is pres- ent for the time of interaction between the atoms and laser radi- a

We report on the direct experimental observation of the 7pP23/2→7dD2 optical transitions in 209 and 210 francium isotopes. By continuously monitoring the fluorescence emitted by the isotopes collected in a magneto-optical trap (MOT), the electric d

24 In recent years interest has been growing into the fascinating properties of dark resonances. Most of the experiments have been carried out in alkali atoms due to their favourable level structure and the commercially available diode lasers, result

An all-optical atomic magnetometer is used to detect a proton free-precession signal from a water sample polarized in a 0.7 T field and remotely analyzed in a 4 $\mu T$ field. Nuclear spins are manipulated either by $\pi/2$ pulses or by non-adiabatic

Rubidium and cesium metal nanoparticles were grown in nanoporous silica samples placed in alkali vapor cells. Their size and shape were investigated by measuring the sample optical transmittance. Spectral changes due to photodesorption processes acti

The results obtained in a cell with a distance between windows on the order of several hundreds of nanometers (the so-called “nanocell”) are presented. The nanocell thickness L in the vertical direction changes from 100 to 900 nm. It is shown tha

The coherent population trapping (CPT) [1] and related electromagnetically induced transparency (EIT) phenomena have found a large number of applications in science and technology. The degenerate two-level systems provide many possibilities for inves

Light-induced desorption and diffusion of alkali atoms embedded in dielectric substrates are experimentally and theoretically investigated. The goal is to realize atomic dispensers fully controlled by light, to study the atom-dielectric interaction a

Recently we observed non-thermal photoejection of atoms embedded in nano-porous silica samples. Alkali atoms are stored inside porous glass matrices and then they are desorbed by ordinary or laser light. In this paper, we present an experimental inve
