Interaction-time-averaged optical pumping in alkali-metal-atom Doppler spectroscopy

Thomas Lindvall, Ilkka Juhani Tittonen

We study the influence of optical pumping on Doppler-broadened alkali-metal-atom $D$ line spectra by solving the time-dependent density matrix for an open two-level system. The time-dependent absorption is averaged over the distribution of interaction times obtained from the three-dimensional beam geometry and atomic velocity distribution and over the longitudinal velocity distribution. The optical pumping is significant at much lower intensities than saturation and depends strongly on the intensity, beam radius, vapor cell length, and spontaneous-decay branching ratio. The result is in agreement with our earlier steady-state solution for a wide range of parameters and predicts two interesting line-shape features.

Study on the abnormal signal in the saturation absorption spectroscopy of sodium atoms

Hu Yuan-hui, J. S. Fu

The abnormal saturation absorption signal of sodium atom D1 line has been observed in different experimental conditions. The explanation has been presented quantitatively using the velocity-selective optical pumping model.

Velocity-selective optical pumping and Doppler-free spectroscopy

M. Pinard, C.G. Aminoff, Franck Laloë

We describe a spectroscopic method combining saturated absorption and Zeeman optical pumping. A weak expanded monochromatic laser beam creates a velocity-correlated orientation in an atomic level without optical saturation. A polarization-modulated counterpropagating detection beam provides signals related to simple atomic observables. Combination with magnetic resonance techniques is described. We have applied this method to metastable states of Ne, with nuclear or electronic orientation. Effects of velocity-changing, depolarization (Kastler- or Dehmelt-type pumping) or metastability exchange collisions are discussed.

We study the influence of optical pumping on Doppler-broadened alkali-metal-atom DDD line spectra by solving the time-dependent density matrix for an open two-level system. The time-dependent absorption is averaged over the distribution of interaction times obtained from the three-dimensional beam geometry and atomic velocity distribution and over the longitudinal velocity distribution. The optical pumping is significant at much lower intensities than saturation and depends strongly on the intensity, beam radius, vapor cell length, and spontaneous-decay branching ratio.
