| Outline of Final Research Achievements |
In this study, we developed a multiphoton ionization mass spectrometer using an ultraviolet ultrashort optical pulse as an ionization source for suppressing the fragment ions and for observing a molecular ion. For this purpose, we studied a method to compress the third harmonic emission of a Ti:sapphire laser. Finally, we could expand the band width of the spectrum and reduce the laser pulse width based on self phase modulation in a rare gas. This laser pulse was used in multiphoton ionization mass spectrometry to study the advantage of this method. This type of approach would be useful for studies of ultrafast phenomena as an advanced spectrometric technique.
