We report the generation of 0.3547-\ensuremath{\mu}m radiation by tripling 1.064-\ensuremath{\mu}m radiation in a phase-matched mixture of rubidium and xenon. We find $\ensuremath{\chi}(3\ensuremath{\omega})=1.4\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}32}$ esu, which is about ${10}^{6}$ times greater than that of He. Phase matching occurs for Xe and Rb atoms in the ratio 412:1.We report the generation of 0.3547-\ensuremath{\mu}m radiation by tripling 1.064-\ensuremath{\mu}m radiation in a phase-matched mixture of rubidium and xenon.

Rb-Xe spin relaxation in dilute Xe mixtures

Ian A. Nelson, Thad G Walker

We present measurements of spin-relaxation of Rb atoms in $\mathrm{He}(98%)\ensuremath{-}{\mathrm{N}}_{2}(1%)\ensuremath{-}\mathrm{Xe}(1%)$ mixtures similar to those used in magnetic resonance imaging polarizers. The pressure dependence allows us to separate out contributions from Rb-Xe van der Waals molecules and binary collisions. For the first time, we observe the predicted increase in the molecular contribution at high pressure. Our data suggest that the deduced molecular breakup rate has a strong temperature dependence.We present measurements of spin-relaxation of Rb atoms in $\mathrm{He}(98%)\ensuremath{-}{\mathrm{N}}_{2}(1%)\ensuremath{-}\mathrm{Xe}(1%)$ mixtures similar to those used in magnetic resonance imaging polarizers.
