Abstract

Abstract : Ultrafast, off‐resonant strong field excitations of semiconductors result in extremely nonlinear, ultrafast, dynamical processes. Those include high‐harmonic and high–order sideband generation, as well as dynamical Bloch oscillations and quasi–particle interferences and collisions. Recently, high–powered light sources have also allowed the study of these phenomena in experiments. This review, presents an overview of the experimental findings, as well as the theory approaches used for their description. Abstract : The excitation of semiconductors with short, off‐resonant, high‐power terahertz pulses yields extremely nonlinear, ultrafast, dynamical processes including very‐high harmonic generation, the occurence of high‐order sidebands, dynamical Bloch oscillations, as well as quasi‐particle collisions. This review overviews the experimental findings and the microscopic theory used for the consistent quantitative analysis of the observations.
