Ultrafast Dynamics of Molecules in Intense Laser-Light Fields: New Research Directions

摘要

In intense laser light fields, molecules undergo a variety of characteristic processes such as alignment along laser polarization direction, dressed-state formation, ultrafast structural deformation, multiple ionization, and Coulomb explosion. The investigation of the dynamical behavior of molecules in intense laser fields has afforded us invaluable opportunities to understand fundamentals of interaction between molecules and light fields as well as to manipulate molecules using characteristics of laser light fields. In the present article, new directions of this rapidly growing interdisciplinary research fields are proposed by introducing our recent studies based on (ⅰ) a quasi-stationary Floquet approach, (ⅱ) a pulsed gas electron diffraction measurement, and (ⅲ) tandem TOF mass spectroscopy.
