Abstract

We demonstrate temporal coherent control in two-photon transitions. A pair of broadband ( Δ λ 20 nm ), ultrashort ( Δ t 100 fs ), collinear pulses with a variable time delay excites the rubidium atoms into the 5 D state from the 5 S ground state where the two-photon transitions are enhanced by the intermediate level 5 P . The excited atoms radiate 5 μm ( 5 D 6 P ) and 420 nm ( 6 P 5 S ) light. As a result of tuning the wavelength of the input laser, a superfluorescence at 420 nm exhibits different temporal behaviors. A switching from a beating at the frequency given by the difference between the sequential atomic transitions that involve the 5 P 3 / 2 intermediate level, to a quantum beating due to two different two-photon excitation paths, 5 S 5 P 1 / 2 5 D and 5 S 5 P 3 / 2 5 D is observed. Based on the simple atom-field interaction theory, an analytic solution, which qualitatively elucidates experimental results, is obtained.
