Interference Between Coherences at 384 THz and 386.1 THz in Rb Observed at 2.1 THz

Abstract

Interference between coherences established at 384 and 386 THz in atomic Rb (5d5/2- 5p3/2 and 5p3/2-5s1/2, respectively) is observed at the 2.1 THz difference frequency. Interaction between the two coherences is observed in the spectral domain in the form of a Fano resonance, and the characteristics of the coupled oscillator are described.
