Abstract

This work is based on previous papers^1,2 which analyzed the resonant magnetooptic spectroscopy. These papers presented theoretical expressions for the atomic Voigt effect and the Faraday effect signal intensity. The theory predicts how the analytical detection sensitivity depends on the Zeeman-split resonance line profile and on the polarization state of the incident light beam. To verify the previous analysis we measured the Voigt effect signal profiles of sodium atoms and OH molecules in a chemical flame, using wavelength-scanned narrowband visible and ultraviolet dye lasers. The laser beam passed through the flame, which was placed in the gap of a magnet. The magnetic field was perpendicular to the optical path. The beam passing through the flame was detected with a polarization analyzer. The observed profiles can be interpreted on the basis of the previous theoretical analysis.
