Using individually shaped three pulses in 2D Fourier transform optical spectroscopy, we retrieve and coherently control the amplitude and phase of the two-photon transition between 5P1/2 and 5P3/2 levels in atomic Rubidium.
We present a method that harnesses coherent control capability to two-dimensional Fourier-transform optical spectroscopy. For this, three ultrashort laser pulses are individually shaped to prepare and control the quantum interference involved in two-photon interexcited-state transitions of a V-type quantum system. In experiments performed with atomic rubidium, quantum control for the enhancement and reduction of the 5P${}_{1/2}\ensuremath{\rightarrow}$ 5P3/2 transition was successfully tested in which the engineered transitions were distinguishably extracted in the presence of dominant one-photon transitions.
