The field of nonlinear optics has been intensely investigated since the advent of the laser in the 1960s. It entails the study of strong light interaction with matter, where exotic effects, such one colour of light converting to another colour, can be realized. Ever improving laser technology and fabrication methods have opened the door to nonlinear optics at very small length scales down to a billionth of a meter, called “the nanoscale”, for myriad applications. Underlying these technological developments is a need to understand the details of how light interacts nonlinearly with materials, and how to use that interaction to design processes and devices for further technological advances.

自20世纪60年代激光器问世以来，非线性光学领域一直受到人们的广泛关注。它需要研究强光与物质的相互作用，在那里可以实现奇异的效果，例如一种颜色的光转换为另一种颜色。不断改进的激光技术和制造方法为非线性光学打开了大门，其长度尺度可低至十亿分之一米，称为“纳米级”，可用于无数应用。这些技术发展的基础是需要了解光如何与材料非线性相互作用的细节，以及如何利用这种相互作用来设计工艺和设备，以实现进一步的技术进步。
