| 摘 要： | 在无序固体掺Er3 玻璃中实施了时间相干控制,对波长为670 nm的上转换荧光进行了调制,荧光强度随着延迟时间的变化而振荡变化,通过拟合得到波包的退相特征时间为300 fs;同时由光子回波信号测得由声子作用引起的波包退相特征时间.上述两个数据的一致性表明波包的快速退相是玻璃基底的声子作用引起的,从而为探索在无序固体中的相干时间控制提供了线索.

| Abstract: | The authors achieved the temporal coherent control in an Er~(3 )-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. |
