This lecture covers the propagation of optical pulses in linear dispersive media, discussing concepts such as group speed dispersion, Gaussian optical pulses, chirp effects, and frequency domain transformations. It also explores the generation of new frequencies in nonlinear dispersive media and the effects of phase self-modulation. The instructor references key textbooks on lasers, femtosecond laser pulses, photonics fundamentals, and nonlinear fiber optics.
