A 1800 gr/mm grating was used to reduce the line width of the laser oscillator which has a wide wavelength over 100 nm, and a tuning mirror was used to tune the wavelength of the laser oscillator to the resonant wavelength of the atomic transition line that was to be ionized. The wavelength range of the Ti:sapphire laser was 730 nm - 850 nm, and output power of approximately 1.1 W (approx. 1.1mJ of energy per pulse) was obtained in the case when pumped by 9.0 W of DPSSL using the self-seeding type. UV oscillation was achieved by second harmonic generation of the Ti:sapphire laser. The wavelength range of UV laser was 380 nm - 420 nm, and the output energy per pulse was approximately 150 uJ when the Ti:sapphire laser was pumped by 1.0 W. In order to detect the Yb photo-ion that was ionized by the UV laser, a mass analyzer that used to be used in the laboratory was partially improved. As a result of the experiment, the resonant ion signal was observed in the 398.8nm wavelength, and it could be concluded that the observed ion signal strength was not smaller than that of the resonance ionization in the visible range
