Development of laser technology (Development of the wavelength tuning and the output stabilization technology)

Various types of the dye laser are developed and investigated for the wavelength tuning and the output stabilization. And a Ti:sapphire laser system was developed to expand the lasing frequency and the injection seeding was executed in this Ti:sapphire laser. New frequency tuning mechanism using a wedge prism was developed and it was proved that better fine frequency tuning can be achieved by rotating the wedge prism instead of the tuning mirror. Efficiency and the parameters of the high power dye laser amplifier system were calculated by the computer simulation. The characteristics of the dye nozzle were examined for the stabilization of the high power, high repetition rate dye laser system and the output characteristics of the dye laser using the nozzle are investigated.
