Pulse Broadening in Dispersive Media

Ultrashort pulses are a promising tool for laser material processing applications. On the one hand, ultrashort pulses often show superiority in e.g. heat control and precision; on the other hand, due to dispersive effects, it can be challenging to maintain the pulse duration after propagation through a complete optical system. In this example, we investigate the relationship between pulse broadening and material dispersion, based on selected examples.
