Chapter 9: Nonlinear Optical Techniques for Nanomaterials Check Access

This chapter aims to provide a comprehensive overview of the latest developments in nonlinear optical techniques applied to nanomaterials, with a focus on recent advancements and future possibilities. Nanomaterials, a pivotal class characterized by high surface-to-volume ratios, increased reactivity, and distinct mechanical, optical, and electrical properties in comparison to their bulk counterparts, have been the subject of extensive research for many years. Their unique characteristics render them promising in various fields, including electronics, energy, catalysis, biomedicine, and photonics. Among the prominent research areas in nanomaterials, nonlinear optics stands out, encompassing the interaction of intense light with matter. Nonlinear optical techniques facilitate the investigation of the interaction between light and matter in the nonlinear regime, allowing the observation of various phenomena, such as frequency conversion, nonlinear fluorescence, nonlinear refraction, and nonlinear absorption. These techniques not only enable precise exploration of the optical responses of nanomaterials, but also pave the way for the development of innovative applications in areas such as electronics, sensing, and photonics.
