With a pump-probe experimental scheme, the ultrafast temporal revolution molecular dynamics of N2 and O2 were investigated at the Free-Electron-LASer in Hamburg (FLASH). Firstly, IR-assisted XUV multiphoton experiment of N2 was performed at FLASH in combination with a synchronized femtosecond optical laser. The fragmentation and multiple ionization dynamics of N2 have been investigated using a Reaction-Microscope (ReMi). We find the sequential ionization is to be the dominant and efficient process for molecules in X-ray regime. The second experiment is that we use the THz electric field to trace the autoionization process happening in molecular oxygen.
