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

Rb optical resonance inside a random porous medium

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

We studied resonant laser interaction with Rb atoms confined to the interstitial cavities of a random porous glass. Due to diffusive light propagation, the effect of atomic absorption on the light scattered by the sample is almost entirely compensate

Light-induced atomic desorption and diffusion of Rb from porous alumina

Autor: Villalba, S., Failache, H., Lezama, A.

We present the first study of light induced atom desorption (LIAD) of an alkali atom (Rb) in porous alumina. We observe the variation due to LIAD of the rubidium density in a vapor cell as a function of illumination time, intensity and wavelength. Th
