| Research Abstract |
Azobenzene single molecules before and after photo-isomerization were observed by a scanning tunneling microscopy. On the metal substrate with strong adsorption interaction, in-plane trans-azobenzene molecules were found, implying the inversion mechanism is dominant. Furthermore, for controlling photo-isomerization or molecular conformation change, optical pulses with spatially-dependent phase and polarization were generated with high efficiency. In addition, using the pulses, nonlinear spectroscopy along a ring shape was established. Metal surface ablation experiments were performed, demonstrating total angular momentum effects.
