This book provides information on various pulse compression techniques in the aspect of theoretical modelling as well as experiment which helps the reader to acquire a knowledge on the basic concepts of pulse compression. It fills a noticeable gap in the field and helps readers understand compression techniques and their physical mechanism through optical fiber. Students, researchers, and scientists in photonics and nonlinear fiber optics all make up the target audience for this book. Key Features: Includes the nonlinear pulse compression techniques to achieve femtosecond/attosecond pulses. Explores topics such as photonic crystal fiber and pulse propagation in the fiber. Includes numerical tools for the analysis of pulse propagation and compression. Discusses applications of ultrashort pulse generation techniques. Provides useful end-of-chapter summaries.
