摘要

本研究首次使用非共线光参量放大器(NOPA)作为光源，在ZnS中观察到相干的LO声子振荡。NOPA的优点是不仅可以在可见光区域内调谐，而且脉冲宽度比传统的光参量放大器短。因此，NOPA适合于观测激子共振附近的相干声子振荡，以研究声子与激子之间的相互作用。

Coherent phonon oscillations in ZnS excited by noncollinear optical parametric amplifier

This study has observed coherent LO phonon oscillations in ZnS for the first time using a noncollinear optical parametric amplifier (NOPA) as a light source. Merits using NOPA are not only tunability in a visible region but also shorter pulse width than those of conventional optical parametric amplifiers. Therefore, NOPA is suitable for observing coherent phonon oscillations near the exciton resonance to investigate the interaction between phonons and excitons.
