强(5.0×10 12W cm−2)纳秒傅里叶合成激光场由无干涉仪的傅里叶合成激光场发生器产生的基频、二次、三次和四次谐光组成，基于定向不对称分子隧道电离(TI)诱导定向选择性电离。激光场生成器运行无调整，稳定性高，重复性好。相位敏感、取向选择性的分子TI提供了一种简单的方法，通过数据拟合分析来估计基频光和每一次谐波之间的相对相位差。傅里叶合成激光场的这种应用不仅将促进光波工程，而且将促进对物质的控制。
Intense (5.0× 10 12 W cm− 2) nanosecond Fourier-synthesized laser fields consisting of fundamental, second-, third-, and fourth-harmonic light generated by an interferometer-free Fourier-synthesized laser field generator induce orientation-selective ionization based on directionally asymmetric molecular tunneling ionization (TI). The laser field generator ensures adjustment-free operation, high stability, and high reproducibility. Phase-sensitive, orientation-selective molecular TI provides a simple way to estimate the relative phase differences between the fundamental light and each harmonic by data-fitting analysis. This application of Fourier-synthesized laser fields will facilitate not only lightwave engineering but also the control of matter.
