By surveying the current and recent investigations on molecules in an ultrashort intense laser field, we elucidate how important these investigations are for fundamental understanding of light-molecule interaction as well as for controlling chemical and biological reaction processes, and propose future research directions in this newly emerging research field.
Recent development of ultrashort pulsed laser technology enabled us to investigate molecules interacting with an intense laser field whose magnitude can even surpasses the Coulomb field within atoms and molecules. From such investigations, it has been shown that molecules exhibit a variety of new phenomena such as alignment/orientation, ultrafast structural deformation, and ultrafast hydrogen migration. Furthermore, by designing intense pulsed laser fields, it has been shown that chemical and biological processes can be controlled. It should also be noted that the generation of attosecond light pulses has been made through the interaction of intense laser pulses with atoms and molecules.
Considering the potential applicability of the recent findings and the advanced laser technologies to wide research areas in chemistry, we will survey the experimental and theoretical investigations on molecules in an ultrashort intense laser field in recent years, elucidate how important these investigations are for fundamental understanding of light-molecule interactions in the ultrashort time domain of femtoseconds and attoseconds as well as for controlling chemical and biological reaction processes, and propose future research directions in this newly emerging interdisciplinary research field.
In addition to an annual meeting of the task group, we plan to hold a school or a workshop for young researchers in a back-to-back form with one of the task group meeting in order to disseminate the activities of the project and to promote the research activities on a worldwide scale under the initiative of the IUPAC Physical and Biophysical Chemistry Division. The contents of the technical report as well as the issues discussed in such a workshop or school will be compiled in a form of a review style book for disseminating the product of the project.
A final report is under preparation.
