| Outline of Final Research Achievements |
Recently, femtosecond laser systems have been realized, which makes us possible to utilize the high intensity laser field to improve conventional laser-induced fluorescence(LIF) systems. By using high intensity laser field, we are possible to control or creat the excited atoms to be measured. So far, LIF method is a powerful diagnostic method, however it strongly depends on the presence of target atoms, and therefore depends on the experimental conditions. We proposed a new active LIF system which controls the excitation state of tatrget atoms by femtosecond laser.
We have experimentally confirmed that the excited atoms are created through non-resonant interaction of femosecond laser light with the atoms. It has been also demonstrated that the created atoms can be measured by LIF system indicating realization of acive LIF sysytem.
