Outline of Final Research Achievements

We have constructed an advanced spectroscopic measurement system using extreme ultraviolet and mid infrared femtosecond laser pulses to track in real time chemical reaction processes of molecules containing hydrogen (proton) which is one of the key elements in the evolution of molecular clouds in interstellar space. In the present study, we have succeeded in developing ultrashort laser pulses at 133 and 80 nm which correspond to the 3rd and 5th order harmonics of the fundamental laser at 400 nm, and applied to time-resolved spectroscopy of ultrafast molecular dynamics with high temporal resolutions.
