在火焰中测量了OH分子后向盒简并四波混频的偏振特性，并与理论进行了比较。不同的激光偏振的信号强度的比率示出超过微扰理论预测的一个封闭的两级系统时，在相互作用体积中形成的光强度光栅。这些结果被证明是不一致的人口非守恒效应，并归因于淬火诱导的热密度光栅的散射。
The polarization properties of backward-box, degenerate four-wave mixing from OH molecules are measured in a flame and compared with theory. Ratios of signal intensities for different laser polarizations are shown to exceed perturbation-theory predictions for a closed two-level system when optical intensity gratings are formed in the interaction volume. These results are shown to be inconsistent with population-nonconserving effects and are attributed to scattering from quenching-induced thermal density gratings.
