Laser processing of nanomaterials: From controlling chemistry to manipulating structure at the atomic scale

Abstract Beginning in the mid-20th century with the invention of a coherent beam of light with precisely controlled emission known as the laser, engineers and scientists have been pushing the boundaries as to the applications of these incredible devices. Utilizing lasers as a tool to manipulate nanomaterials opens the possibility of creating unique chemistries, structures, devices, and architectures by controlling the light–matter interactions within the material. In this chapter, we provide an introduction into these light–matter interactions at the nanoscale to include laser heating, ablation, and plasmonics, provide examples of nanochemistries achievable through this technique, and discuss applications for future implementation to include film transfer, nanostructuring, and device implementation.
