N2 - We investigated a pump scheme to establish a practical Ar2 excimer laser operating at 128 nm. In this scheme, electrons generated by preionization of Ar gas at high pressure were heated by intense pulsed CO2 laser radiation. The resultant high-density plasma in the high-pressure Ar gas was used to create excited Ar dimers, In the experiment, a CO2 laser beam from a transversely excited atmospheric CO2 laser was focused on a narrow line, 100 mm in length, in Ar gas at a pressure of 2 MPa. A vacuum ultraviolet (VUV) signal was observed only when the Ar was preionized, and the VUV signals were identified as the emission of Ar2 excimers from the features of the spectrum which was centered on 128 nm.
