Dynamics of molecules and materials in intense laser fields
Optical properties and molecular response are fundamental to all phenomena of materials in intense laser fields. We measure the photon emission and ion/electron fragments to investigate the dynamics of the interaction. Mechanisms of electronic motion and molecular reaction are to be revealed from the study.
