This Perspective highlights recent advances in linear and nonlinear spectral nanoimaging. The described developments are motivated by the need to characterize molecular and material systems noninvasively with nanometer spatial and femtosecond temporal resolution. Indeed, the ability to image and chemically characterize heterogeneous interfaces with joint nano–femto resolution is a prerequisite to advancing our fundamental understanding of processes as diverse as heterogeneous catalysis, microbial communication, and energy flow in pristine/defect-containing low-dimensional quantum materials, to name a few. We describe pioneering work and recent demonstrations of (non)linear optical nanoimaging and nanospectroscopy, with an emphasis on high spatial resolution measurements conducted under ambient laboratory conditions.

多模式(非)线性光学纳米成像和纳米光谱

这个观点重点介绍了线性和非线性光谱纳米成像的最新进展。所描述的发展是由于需要以纳米空间和飞秒时间分辨率无创地表征分子和材料系统。事实上,以纳米-毫微微分辨率对异质界面进行成像和化学表征的能力是推进我们对原始/缺陷低维量子材料中的异质催化、微生物通讯和能量流等过程的基本理解的先决条件,仅举几例。我们描述了(非线性)线性光学纳米成像和纳米光谱的开创性工作和最近的演示,重点是在实验室环境条件下进行的高空间分辨率测量。
