Section 3: Dispersion and Dispersion Compensation

Management of dispersion is key to obtaining ultrashort pulses. For example, in chirped pulse amplification (CPA), stretching pulses temporally is crucial to avoiding the nonlinearities involved with high peak power, which were limiting the amplified powers achievable before CPA was demonstrated. Additionally, in order to recover an ultrashort pulse, compression is needed to eliminate the phase lengthening the pulse. There are also so many other places where dispersion enters the conversation: literally, any time light interacts with matter! We will go through some background first of the “foundations” of dispersion, and then go through some useful tools for managing the dispersion in your life, so stay tuned!
