Abstract：The authors achieved the temporal coherent control in an Er3+-doped telluride glass，one kind of disordered solids. The upconversion at 670 nm was modulated and the dephasing time was simulated as 300 fs. Moreover，the photon echo signal gave the dephasing time due to the phonon interaction. The agreement between the two data indicates that the interaction between the wavepacket and the phonon leads to the fast disappearance of wavepackets interference，which is helpful for the technique to be applied to the disordered solids.
