| Research Abstract |
We have investigated coherent dynamics of molecules ionized in intense laser fields. (1) Photoelectron and photoion coincidence momentum imaging of ethanol and O_2 and (2) spectroscopic detection of rotational state distribution of neutral NO, which survive the ionization by an intense laser pulse, have been performed successfully and the dependence on the laser intensity and pulse width has been revealed. In addition, (3) a broad band vacuum ultraviolet pulse source has been constructed toward ultrafast reaction probing.
