Grating Stretcher for Ultrashort Pulses
Abstract
The role of ultrashort pulses is growing in modern optical applications. For example, they can be found in the fields of laser material processing, medical imaging, optical communication and so on. Prisms and gratings are typical optical components that are used for manipulating the temporal behavior of optical pulses. In this example, a pulse stretcher consisting of two diffractive gratings are constructed and the pulse broadening effect after propagation through them is demonstrated.

Use Case
Pulse Focusing with High-NA Lens
We investigate the effects of subjecting an ultrashort pulse to propagation through a lens with high numerical aperture, in terms of its spatial, as well as of its temporal, profile.
Use Case
Pulse Broadening in Dispersive Media
We investigate the relationship between the broadening of an ultrashort pulse and the dispersion of given materials that the pulse propagates through.
