抜粋

We report the first decoherence control of excitons which was performed on the model semiconductor GaSe by using successive three femtosecond pulses, i.e., the six-wave mixing configuration. The second pulse acts as a π pulse which reverses the time evolution of non-Markovian dynamics. By changing the pulse interval conditions, we confirmed the suppression of exciton decoherence by π pulse irradiation. From the analysis of the decoherence, it is also found that the six-wave mixing technique can successfully be applied to determine the reservoir parameters.
