he absorption profiles of left-hand and right-hand circularly polarized laser light propagating through sodium vapor are asymmetric and considerably frequency shifted if small static magnetic fields are present. Using an analytical model we show how optical pumping ‘‘enhances’’ the laser-induced light shift from the kilohertz to the gigahertz range. We compare the analytical results with experimental data obtained from the homogeneously broadened Na D1 transition.

Depolarization of optically pumped sodium atoms by wall surfaces

Masayoshi TANAKA, T. Ohshima, K. Katori +4 more

The polarizations of sodium atoms optically pumped by a single-mode cw ring dye laser were measured as a function of the pumping power, sodium-vapor thickness, and external magnetic field for Pyrex glass and copper walls with and without dry-film coating. Observed quantities were analyzed by a simple optical pumping model in which the effect of the radiation trapping was taken into account. Assuming that the depolarization of the sodium atom was mainly induced by the local magnetic field at the sodium atom during its adsorption on the wall surface, the calculations could successfully reproduce the observed polarizations.
