In recent years, following intensive research on new type of laser using group Ⅰ A diatomicmolecules and group Ⅳ A diatomic molecules, investigations on the vuv/xuv lasers utilizingalkali-halides ionic excimer formed by Ⅰ A-Ⅶ A combination and Rare--gas Alkali ionic excimerformed by Ⅰ A-Ⅷ A combination have been carried out. On the basis of the above-mentionedresearch, the Institute of Opt--Electronics, Harbin Institute of Technology first suggested an NaSsystem formed by ⅠA-Ⅵ A element combination. Because of the low excitation threshold of Na
