英文摘要
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.
