Outline of Final Research Achievements

A laser plasma source, which can generate continuously repetitive pulses, has been developed for a novel compact and powerful VUV source. We successfully developed a one-dimensionally translating substrate system with a closed He gas cryostat that can continuously supply various cryogenic targets for ~10 Hz laser pulses. Solid Ar, Kr and Xe layers were formed and a Nd:YAG Q-switched laser irradiated them, it was shown that stable output power was achieved continuously from the plasma emission at frequencies of 1-10 Hz. VUV Spectra of these emissions showed specific ion’s lines on continuous broad emissions.
