Pulse Focusing with High-NA Lens

Abstract


While for most other types of sources it is often accurate enough to labour under the stationary approximation, ultrashort pulses require a somewhat more nuanced approach, where the correlation between the different spectral modes is taken into account. We investigate here the effects of subjecting one such pulse to propagation through a lens with high numerical aperture, in terms of its spatial, as well as of its temporal, profile.

Use Case

Femtosecond Pulse Propagation through Dispersive Seawater

The propagation of a 5-fs pulse through seawater is studied in VirtualLab Fusion. The broadening of the pulse and the change in its temporal profile due to dispersion of the material are shown.

Focusing of Femtosecond Pulse by Using a High-NA Off-Axis Parabolic Mirror

The focusing process of a 10-fs pulse by using a high-NA parabolic mirror is modeled and both the spatial and temporal behaviors are investigated...
