The interference between the emission originating from the short and long electron quantum paths is intrinsic to the high harmonic generation process. We investigate the universal properties of these quantum-path interferences in various generation media and discuss how ionization effects influence the observed interference structures. Our comparison of quantum-path interferences observed in xenon, argon, and neon demonstrates that our experimental tools are generally applicable and should also allow investigating more complex systems such as molecules or clusters.
源于短电子量子路径和长电子量子路径的发射之间的干涉是高次谐波产生过程所固有的。我们研究了这些量子路径干涉在各种产生介质中的普遍特性，并讨论了电离效应如何影响所观察到的干涉结构。我们对在氙、氩和氖中观察到的量子路径干涉进行的比较表明，我们的实验工具具有普遍适用性，也应该能够用于研究更复杂的系统，如分子或团簇。
