Nonlinear Optics: Introduction

This lecture on nonlinear optics provides a historical overview, starting from John Kerr's discovery in 1875 to the prediction and demonstration of solitons in fibers. It covers applications in laser technology, ultrafast optics, wavelength conversion, optical communication, imaging, and remote sensing. The course focuses on the Optical Kerr Effect and includes modules on third-order nonlinear parametric processes, self-phase modulation, solitons, modulation instability, and supercontinuum generation.
