Ultrafast lasers: modelocking

This lecture covers the principles of modelocking in ultrafast lasers, including active AM and FM, passive modelocking, and Carrier Envelope Frequency for optical clocks. It also discusses the relationship between the width in the time and spectral domains, as well as the statistical definition of width. The lecture delves into the minimum pulse duration of different mode-locked lasers and provides examples of experimental spectra. Additionally, it explores chirped pulses and the design considerations for fiber coupling with high-power laser diodes.
