在四波混频实验中测量了几种气体的非共振三阶非线性介电系数。这些系数被用来计算聚焦激光光束中气体产生的三次谐波辐射量。尽管预测的最小可检测信号是可检测信号的104倍以上，但从未从气体中看到可与噪声区分的信号。
The nonresonant third order nonlinear dielectric susceptibility coefficients of several gases were measured in a four wave mixing experiment. These coefficients were used to calculate the amount of third harmonic radiation generated in gases in a focused laser beam. No signal distinguishable from noise was ever seen from gases, although more than 104 times the minimum detectable signal was predicted.
