Spectroscopy by saturable reflection (A)

S. Le Boiteux, Pierre Simoneau, Daniel Bloch +1 more

Doppler-free spectra of gas phase atoms near a glass-vapour interface are obtained by monitoring the reflection of a probe beam-instead of its transmission-in three-level saturation spectroscopy. Experiments performed on the 3S-3P-4D cascade system of Na have allowed the authors to monitor two-photon-induced saturated dispersion of Na atoms.

A theoretical analysis of sub-Doppler molecular saturation spectroscopy by use of a confocal Fabry–Perot (CFP) cavity is presented. The effects of gas pressure, cavity length and mirror reflectivity on the saturation dip amplitude are analysed. Such a treatment can provide the optimum conditions and a guidance for the experiment of saturating the weak molecular absorption lines.
