| Outline of Final Research Achievements |
A two-color near-infrared femtosecond pump beam (800 and 1200 nm) and a one-color ultraviolet femtosecond probe beam (200 or 267 nm) were focused into a hydrogen gas to generate an ultrashort optical pulse in the 154 - 400 nm region. The laser pulse was used as an ionization source in mass spectrometry, and a molecular ion was found to be significantly increased. The mass spectrometer was applied to several samples, e.g., nitro compounds in PM2.5 extracted from the ambient air, an explosive attached to a human blood, and nerve agent metabolites in a human urine to demonstrate the advantage of the analytical method developed in this study.
