Outline of Final Research Achievements

We have developed a new time-dependent density functional method based on FFT for atoms, molecules, clusters and nano-particles in a strong laser field. Based on the method, we have investigated the ionization and dissociation processes of hydrogen molecules, oxygen molecules in an intense laser field and based the understanding we proposed a way to control the dynamics processes by intense lasers. Meanwhile, to cope with the researches on the generating a circularly polarized attosecond pulse, we have investigated the related processes, atomic ionization in two-color circularly polarized laser fields and our results are in good agreement with experiments. Specially, we have developed a theory to treat the photo-ionization and photo-excitation of atoms in a strong elliptically polarized field in a unified way and the method can be used for many dynamics processes.
