Ultrathin atomic vapor film transmission spectroscopy: analysis of Dicke narrowing structure

Yuanyuan Li, Yanpeng Zhang, Chenli Gan

Transmission sub-Doppler spectroscopy with confined atomic vapor film between two dielectric walls is theoretically studied. Because of atoms flying from wall to wall, where they get de-excited, the atom-field interaction time is anisotropic so that the contribution of slow atoms is enhanced, a sub-Doppler transmission spectroscopy (Dicke narrowing effect) can be obtained when the thickness of the film is much small or comparable with the wavelength even at small angle oblique incidence. It is feasible to get a sub-Doppler structure in a new region (L < ?/4) in experiments.Transmission sub-Doppler spectroscopy with confined atomic vapor film between two dielectric walls is theoretically studied.

Sub-Doppler Spectroscopy by Using Sodium Nanocell

E. Mariotti, Alen Khanbekyan, Alen Khanbekyan +7 more

We present for the first time the results of the sub-Doppler spectroscopy realized with a nanocell filled with a Sodium metal. The thickness L of the gap between the windows (which determines the length of the atomic vapor column) has a wedge in the vertical direction varying from 100 to 900 nm. It is demonstrated that the use of a nanocell with the thickness L=lambda/2 and L=lambda, where lambda is the wavelength of the dye laser radiation resonant with D2 line of Sodium, allows one to provide sub-Doppler spectroscopy of the Transmission and Fluorescence spectra of D2 lines of Sodium (lambda ~ 590 nm). A cw dye laser radiation with the linewidth of ~1 MHz and tunable in the range of several GHz has been usedWe present for the first time the results of the sub-Doppler spectroscopy realized with a nanocell filled with a Sodium metal.
