Abstract
The atmospheric oxygen band, b1Σ+g (υ'=0)-X3Σ-g (υ″=0), was detected by the resonant Voigt-effect (optical anisotropy induced in a transverse magnetic field), using a titaniumdoped sapphire laser as a light source. Elliptically polarized light was tuned to the rotational lines of this band. The polarization state of light after passing through the air was analyzed with an angle-offset birefringent prism. By adjusting the light ellipticity and the analyzer offset angle, the signal of the pP (1, 1) line was obtained with a signalto-noise ratio of 1×102 for oxygen molecules in the air of 4-cm optical path at 1-atm pressure.
