Two-Photon Hanle Effect in Ramsey Interrogation

摘要: We have recently reported [1] a homogeneous linewidth version of the nonlinear Hanle effect. The two—photon interaction creates coherence between Zeeman sublevels, when polarized laser radiation excites components an optical transition with ΔM=±l selection rules. When degeneracy M sublevels is removed by external field B, cancelled, causing decrease in saturation,and it possible to record increase absorption. shape effect directly determined level which removed, and insensitive bandwidth effects (the saturating only acts as coupler sublevels).
