- Abstract
A new pump scheme for the realization of a practical Ar[sub 2] excimer laser operating at 126 nm has been proposed and investigated experimentally. In this scheme, pre-ionized high-pressure Ar gas was excited by an intense transversely-excited atmospheric (TEA) CO[sub 2] laser irradiation. A 100-mm-long line plasma was successfully produced at an argon gas pressure of 2 MPa. The vacuum ultraviolet emission at 126 nm from the Ar[sub 2] excimers was observed and its emission characteristics were investigated under various experimental conditions.
