Coherence control in a _ -type three-level system having an ultrafast (<10 fs) dephasing time has been demonstrated. Coherences in the multilevel system were excited by an intense supercontinuum yielding terahertz Rabi frequencies. The coherence was controlled by changing the interaction phase between the excited coherences and the broadband light field in the double-pulse pumping scheme.
