Chirped Pulse Amplification: Ultrashort Laser Pulses

This lecture covers the principles of chirped pulse amplification (CPA) for generating ultrashort laser pulses, including the use of stretched pulses, amplification, and pulse compression. It also discusses the significance of Carrier-Envelope Phase (CEP) stabilization in CPA systems and the performance of different passive CEP stabilization methods. The lecture delves into the physical origin of phase offsets in parametric interactions and the importance of phase matching for efficient nonlinear optical processes. Additionally, it explores the application of CPA in various laser sources and the challenges in achieving phase matching in different media.
