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