Two color polarization spectroscopy in indium vapor cell — •Jae-Ihn Kim and Dieter Meschede — Institute for applied physics, University of Bonn, Wegelerstr.8, 53115 Bonn

Polarization spectroscopy in a multi level Λ system is demonstrated. The In Λ transition, 52P1/2 - 62S1/2 - 52P3/2, is driven with a violet 410 nm and a blue 451 nm lasers. On contrast to typical polarization spectroscopy where one laser frequency is used, violet light with circular polarization was used as pump beam and blue light with linear polarization was only used as probe beam. We find dispersive resonance line with another sharp dispersive line at the center. The expected line-shape was calculated by a simplified 3 level model including velocity changing collisions.
