K. Ohmori thanks Prof. Elmar Schreiber (Princeton University) for his friendship and a helpful guidance to the fantastic femtoworld. K. Ohmori also thanks Prof. Masaki Yamamoto (Tohoku University) for stimulating discussion about the applications of the attosecond optical-phase manipulation. This research was partly supported by the Grant-in-Aid for Scientific Research on Priority Areas “Molecular Physical Chemistry” and by the Grant-in-Aid for Science (No. 11640383) from the Ministry of Education, Science, Sports, and Culture.

N2 - We have developed the "attosecond phase modulator" (APM) for the manipulation of optical phases with an accuracy of attoseconds. The interference of two 300 fs laser pulses at 252 nm has been taken by using this APM; the time delay between those two pulses is tuned with an accuracy of attoseconds by APM to induce constructive and destructive interferences. The interferogram measured by scanning the time delay shows a high-frequency oscillation with a period of 840 as. Quantum mechanical calculations have been performed to demonstrate that APM is useful in manipulating the relative phase of two nuclear wave packets created in a single molecule and controlling their interference with an accuracy of attoseconds. Applications of such an ultraprecise phase-manipulation technique are discussed to propose a possible new field of science and technology which we call the "attosecond wave-packet engineering".
