The objective of this chapter is to provide a review of the main fundamental linear and nonlinear processes excited by ultrafast lasers in different kinds of materials with the aim to reveal and highlight possible mechanisms, which would enable extreme localization of energy absorption. After summarizing existing knowledge on laser-induced phenomena that includes mechanisms of laser light absorption, heat transfer peculiarities, energy thermalization at ultrafast time scales, and related hydrodynamic phenomena, an overview is given on novel insights into highly nonequilibrium processes gained in recent years via quantum and molecular dynamics simulations. The fundamental part is followed by an analysis of possible techniques and processes, which could enable extreme localization of laser energy absorption both on the surface of material samples and in the bulk.
