The coherent control of optical phonons has been experimentally demonstrated in various physical systems. While the transient dynamics for optical phonons can be explained by phenomenological models, the coherent control experiment cannot be explained due to the quantum interference. Here, we theoretically propose the generation and detection processes of the optical phonons and experimentally confirm our theoretical model using the diamond optical phonon by the doublepump-probe type experiment.
光学声子的相干控制已在各种物理系统中得到实验证明。虽然光学声子的瞬态动力学可以用唯象模型来解释，但由于量子干涉，相干控制实验无法得到解释。在此，我们从理论上提出了光学声子的产生和探测过程，并通过双泵浦-探测型实验，利用金刚石光学声子对我们的理论模型进行了实验验证。
