Saturation and Detuning Effects of Pump Waves in VUV Generation by Resonant Sum Frequency Mixing in Hg

Abstract
Saturation and detuning effects on VUV generation are observed in resonance sum frequency mixing in Hg. The results demonstrate that the mechanism of VUV generation is different above and below 9p1P1 at 79964.1 cm-1 and that higher order effects in the pump and probe powers should be taken into account.
