Abstract

We present measurements of coherence times of excited states of hydrogen-like arsenic impurities in germanium (Ge:As) using a table-top 2D-TDS system. We observe coherent population transfer and decay of transitions from the 2p0 and 2p± states by fitting the detected coherent nonlinear response with the known intracenter transition frequencies. Coherences between excited electronic states that are not visible via conventional single frequency pump-probe measurements are also observed in the off-diagonal resonances in the 2D frequency-domain map.
