This book presents the underlying physical picture and an overview of the state of the art of femtosecond supercontinuum generation in various transparent solid-state media, ranging from wide-bandgap dielectrics to semiconductor materials, and across various parts of the optical spectrum, from the ultraviolet to the mid-infrared. A particular emphasis is placed on the most recent experimental developments: multioctave supercontinuum generation with pumping in the mid-infrared spectral range, spectral control, power and energy scaling of broadband radiation and the development of simple, flexible and robust pulse compression techniques, which deliver few optical cycle pulses and which could be readily implemented in a variety of modern ultrafast laser systems. The expected audience includes graduate students, professionals and scientists working in the field of laser-matter interactions and ultrafast nonlinear optics.
