Doppler-free spectroscopy using two counter-propagating dual-frequency laser beams in alkali vapor cells has been demonstrated recently, providing the detection of high-contrast sign-reversed natural-linewidth sub-Doppler resonances. However, to date

Doppler-free spectroscopy on Cs D$_1$ line with a dual-frequency laser

Autor: Hafiz, Moustafa Abdel, Coget, Grégoire, De Clercq, Emeric, Boudot, Rodolphe

We report on Doppler-free laser spectroscopy in a Cs vapor cell using a dual-frequency laser system tuned on the Cs D$_1$ line. Using counter-propagating beams with crossed linear polarizations, an original sign-reversal of the usual saturated absorp
