Subnatural linewidth effects in non-stationary velocity-selective optical pumping

Wojciech Gawlik, J. Kowalski, Frank N. Trager +1 more

Signals with subnatural linewidths observed in a polarisation spectroscopy experiment on sodium have been investigated under various experimental conditions. The authors find that the mechanism responsible for the subnatural structures is based on non-stationary velocity-selective optical pumping. It is discussed in the light of the presented measurements and a theoretical analysis. Possible spectroscopic applications are considered.

Polarization-rotation resonances with subnatural widths using a control laser

Sapam Ranjita Chanu, Kanhaiya Pandey, Vineet Bharti +2 more

We demonstrate extremely narrow resonances for polarization rotation in an atomic vapor. The resonances are created using a strong control laser on the same transition, which polarizes the atoms due to optical pumping among the magnetic sublevels. As the power in the control laser is increased, successively higher-order nested polarization-rotation resonances are created, with progressively narrower linewidths. We study these resonances in the D 2 line of Rb in a room temperature vapor cell, and demonstrate a width of for the third-order rotation. The physical basis for the observed resonances is that optical pumping results in a simplified ΛV-type level structure with differential dressing of the levels by the control laser , which is why the control power has to be sufficiently high for each resonance to appear. This explanation is borne out by a density-matrix analysis of the system. The dispersive lineshape and subnatural width of the resonance lends itself naturally to applications such as laser locking to atomic transitions and precision measurements.

As the power in the control laser is increased, successively higher-order nested polarization-rotation resonances are created, with progressively narrower linewidths.

The physical basis for the observed resonances is that optical pumping results in a simplified. AV-type level structure with differential dressing of the levels by the control laser, which is why the control power has to be sufficiently high for each resonance to appear.
