Recently proposed universality of the nonlinear response is put to the test and used to improve a previously designed model for xenon. Utilizing accurate measurements resolving the nonlinear polarization and ionization in time and space, we calibrate the scaling parameters of the model and demonstrate agreement with several experiments spanning the intensity range relevant for applications in nonlinear optics at near-infrared and mid-infrared wavelengths. Applications to other species including small molecules are discussed, suggesting a self-consistent way to calibrate light-matter interaction models.
最近提出的非线性响应的普遍性受到了检验，并被用于改进先前设计的氙模型。利用能够在时间和空间上分辨非线性极化和电离的精确测量，我们校准了模型的缩放参数，并证明与跨越近红外和中红外波长非线性光学应用相关强度范围的几个实验结果相符。还讨论了该模型在包括小分子在内的其他物种上的应用，这为校准光与物质相互作用模型提供了一种自洽的方法。
