We report experiments which indicate that the 3547 → 1182Å conversion efficiency in Xe-Ar mixtures is limited by Kerr-induced dispersion to about 0.9 percent. The mixed frequency third-order nonlinearity <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\chi^{(3)}(-3\omega, 3\omega, -\omega, \omega</tex> ) significantly alters the index of refraction at 1182 Å in the presence of large power densities at 3547 Å, affecting phase matching. We suggest using a Xe-Mg-Ar mixture to reduce the effect, thus permitting increased efficiencies.
