We present the variation of intensity in Doppler-free hyperfine lines for rubidium atoms with the application of magnetic field. Different polarization configurations have been studied systematically with varying magnetic fields. There is a significant increase in the intensity variation with applied magnetic field related to different polarization configurations. These variations are explained with the theoretical calculations. The calculations are performed by adopting Nakayama's four level model with the varying magnetic field induced transition probability. © Published under licence by IOP Publishing Ltd.

Line shapes in polarization spectroscopy for the rubidium D1 line in an external magnetic field

Zeeman splitting in the D2 line of rubidium atoms ( 87Rb and 85Rb) has been studied using 'Doppler broadened' as well as 'saturation absorption spectroscopy'. While a linearly polarized beam was used for the former experiment, in the latter case a (π, σ±) polarization configuration was employed for both pump and probe beams. Zeeman lines have been observed by applying a field up to 5 mT. The field variation of relative line intensities in Doppler-broadened spectrum was determined following Tremblay et al and Nakayama's four-level model. For the saturation spectrum, a four-level model was used. Because the enhancement of absorption at the field is as low as 1 mT, the Fg ≤ 2 to Fe ≤ 3 transition for 87Rb can be used as the reference for laser locking. Level crossing is observed in 85Rb at fields less than 5 mT. © 2007 IOP Publishing Ltd.
