We have been developing high intense vacuum ultraviolet (VUV) radiations for the advanced applications such as micro and precise processing and photochemical reactions. We had proposed a noval VUV laser system to generate sub-ps pulses at the wavelength of 126nm. A seed pulse was successfully generated by the 7th-harmonics of 882nm-Ti:sapphire laser in the Xe gas medium. The Ar2 excimer media generating by the optical-field-ionization plasma pumped by another 780nm TiS laser and we could produced a gain of gl=6 at 126 nm. Now, the seed pulses will be amplified in this OFI-produced Ar2 media to micro-joule level.
