Abstract

We have demonstrated a sensitive and versatile new technique of Doppler-free saturation spectroscopy, which takes advantage of Polarization Intermodulated Excitation (POLINEX): the nonlinear interaction of two laser beams in an absorbing medium is studied by modulating the polarization of one or both beams. When the combined absorption depends on the relative polarization of the two beams, an intermodulation is observed in the total rate of excitation. In first exploratory experiments we have studied excited helium atoms in a positive column discharge [1], neon atoms in radiofrequency discharges [1,2], and copper atoms in a hollow cathode discharge [3]. Both optogalvanic detection and fluorescence detection have been used. Clean spectra free of Doppler-broadened background could be recorded despite velocity changing elastic collisions.
