Abstract
We have developed a vacuum ultraviolet (VUV) lamp at 134 nm with a quasi-po int emission geometry using a quasi-continuous-wave (cw) gas jet discharge of an Ar/Kr gas mixture. We have unambiguously identified a new emission co ntinuum centered at 134 nm as a transition of Ar-Kr hetero-nuclear excimers (ArKr*). The VUV emission power of the 134 nm continuum was 10 mW at 21 at m of the total Ar/Kr stagnation gas pressure, at a Kr concentration of 0.1% . Characteristic energy transfer between atoms and dimers plays an importan t role for the efficient production of ArKr* in such a gas jet discharge.
