| Outline of Final Research Achievements |
In this research, we have developed sub-10 fs pulse-shaping technique with a programmable spatial light modulator, negative chirp mirrors and a pair of glass wedges. Using three shaped pulses with optimized temporal modulations, we could successfully demonstrate the coherent control of multiple high-frequency phonons in 4H-SiC. In case of benzenethiol self-assembled monolayer samples adsorbed on Au film, we sensitively measured the frequency-shift of high frequency molecular vibrations, which originates from the interaction with its substrate.
