Sub-Doppler resonances in the back-scattered light from random porous media infused with Rb vapor

Autor: Villalba, S., Laliotis, A., Lenci, L., Bloch, D., Lezama, A., Failache, H.

We report on the observation of sub-Doppler resonances on the back-scattered light from a random porous glass medium with rubidium vapor filling its interstices. The sub-Doppler spectral lines are the consequence of saturated absorption where the inc

Magnetometer suitable for Earth field measurement based on transient atomic response

Autor: Lenci, L., Barreiro, S., Valente, P., Failache, H., Lezama, A.

We describe the development of a simple atomic magnetometer using $^{87}$Rb vapor suitable for Earth magnetic field monitoring. The magnetometer is based on time-domain determination of the transient precession frequency of the atomic alignment aroun

The sensitive detection of either static or radio-frequency \textsc{(rf)} magnetic fields is essential to many fundamental studies and applications. Here, we demonstrate the operation of a cold-atom-based, \textsc{rf} magnetometer in performing {1-D

International audience; We studied a novel spectroscopy setup where alkali atoms are infused in random micro-porous glass and the light probing the atoms have a diffuse nature after the propagation in this strong scattering medium.
