项目摘要
We have developed single-shot time-frequency imaging spectroscopy with an echelon mirror, for visualizing ultrafast wavepacket propagations in time-frequency space. Using this new spectroscopy combined with pulse-shaping techniques, the phonon-polariton propagations of ferroelectric materials and graphene were successfully detected. In graphene, we found that the coherent nano-scale optical-phonon wavepacket can be excited by an impulsive excitation of inter-Dirac-cone scattering at graphene edges. On the other hand, in ferroelectric LiNbO3, we could coherently control the backward- and forward-propagating phonon-polaritons by double pump excitations.
我们已经开发了带有梯形镜的单次时频成像光谱,以可视化时间频空间中的超快波袋传播。使用这种新的光谱与脉搏成形技术结合使用,成功检测到铁电材料和石墨烯的声子 - 果仁传播。在石墨烯中,我们发现连贯的纳米尺度光量波袋可以通过对石墨烯边缘的旋转间旋转散射的冲动激发而激发。另一方面,在铁电linbo3中,我们可以通过双泵激发连贯地控制向后和前向的声子 - 两极。
