A large increase in atomic absorption due to coherent interaction with resonant radiation is
predicted for a closed transition between two degenerate atomic levels verifying 0< F g< F e …

Recent years have seen vast progress in the generation and detection of structured light,
with potential applications in high capacity optical data storage and continuous variable …

We have compared coherent population trapping (CPT) resonances, both experimentally
and theoretically, for excitation of the D_1 and D_2 transitions of thermal Rb85 vapor …

The absorption spectrum of a weak probe, interacting with a driven degenerate two-level
atomic system, whose ground and excited hyperfine states are F g, e, can exhibit narrow …

Recently a scheme has been proposed for detection of the structured light by measuring the
transmission of a vortex beam through a cloud of cold rubidium atoms with energy levels of …

Experimental examination of the coherent population trapping that can be established on
the D1 and D2 lines of Rb at a single hyperfine transition using the Zeeman sublevels of the …

Coherent spectroscopy of degenerate two-level systems of the Doppler-broadened D 2
cesium line has been performed in vacuum and in buffer gas cells. Subnatural-width (SNW) …

The ground-state Hanle effect (GSHE) in alkali-metal atomic vapor using a single circularly
polarized light wave underlies one of the most reliable and simple techniques of modern …

We have studied the ground-state Hanle effect (GSHE) excited by linearly polarized laser
light on the D 1 line of cesium atoms. We have solved algebraically the Liouville equation …

We have analyzed the Hanle effect on the closed F g= 3→ F e= 4 D 2-line transition of 85
Rb. Exciting the rubidium atoms by circularly polarized laser light, and scanning an applied …
