Laser Pulse Amplification and Compression

This lecture covers topics related to laser pulse amplification and compression, including third harmonic generation, optical parametric generator and amplifier, pulse characterization, continuum generation, and phase measurement. It also discusses the operation of regenerative amplifiers, multi-pass amplifiers, and chirped pulse amplifiers, as well as the generation of second and third harmonics. The instructor explains the principles behind semiconductor lasers, pulse generation, and modulation techniques, such as passive mode-locking. The lecture delves into the physics of semiconductors, electron-hole interactions, and optical transitions. It also explores the concepts of gain curves, dispersion curves, and the generation of high-energy pulses through laser amplification and compression.
