Abstract

We report an experimental investigation of collisional depolarization of the atomic cesium 6s2S1/210s2S1/2 two-color two-photon polarization spectrum. The Ar pressure dependence of the spectrum revealed strong depolarization in the vicinity of the 6s2S1/26p2P3/210s2S1/2 stepwise resonances using short pulse pump-probe technique. The linear polarization degree was measured with the first laser tuned to resonance and the second laser tuned within a \pm 11 cm1 range. In the absence of collisions, the measured polarization spectrum is in excellent agreement with calculations. The polarization measurement on the 6s2S1/26p2P3/210s2S1/2 transition and an overview of the experimental techniques of our results are also presented.
