Ultrafast pulse characterization: optical techniques

This lecture covers the principles and applications of ultrafast pulse characterization using optical techniques, including pulse propagation through media, pulse measurement methods, and pulse autocorrelation. The instructor explains the concepts of amplitude envelope, carrier frequency, and phase in the context of laser fundamentals and engineering applications. Various optical devices such as autocorrelators and streak cameras are discussed, along with their role in pulse propagation and detection. The lecture also delves into the complexities of pulse propagation through dispersive media and the challenges of pulse characterization in different materials.
