Abstract
We have frequency-stabilized a single-mode dye laser by using laser-in duced polarization effects in sodium vapour. Birefringence is induced by a resonant polarized pump beam, and this results in dispersion of a weak circularly polarized probe beam. The dispersion signal around th e resonance frequency is then used to generate the correcting signal f or frequency stabilization.
