Focusing of Femtosecond Pulse by Using a High-NA Off-Axis Parabolic Mirror
Abstract
To fully characterize the focusing behavior of an ultrashort pulse, different electromagnetic properties must be considered. That includes both spatial distribution, temporal / spectral distribution, vectorial effect, and the possible coupling amongst all the above. As an example, the focusing process of a 10-fs pulse by using a high-NA parabolic mirror is modeled in VirtualLab Fusion, and both the spatial and temporal behaviors are investigated.

Use Case
Grating Stretcher for Ultrashort Pulses
We set up a pulse stretcher consisting of two diffractive gratings and investigate the pulse broadening effect induced by the interaction of the pulse with the gratings.
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.
