We report on laser-induced vaporization of mercury as a simple tool to increase the efficiency of a resonant 4-wave mixing process to produce VUV radiation near 125 nm. The specificity of this new nonlinear medium is discussed for the best experimental conditions giving a high density of ground state Hg atoms in a column-shape plume. Modification of phase-matching conditions is demonstrated in agreement with VUV profile simulations.
