Interference Effects for Symmetric SSTF-Setups

Abstract

“Simultaneous spatial and temporal focusing” (SSTF) is a well known approach where light is spectrally widened with a stretcher setup and is then focused with a lens to get a focal spot that has a minimal size in space and time domain. This approach however, leads to a tilt of the pulse front, creating an asymmetric field distribution in the focus. To correct this behavior a symmetrized approach is show, utilizing two mirrored paths and the resulting interference effects are analyzed.

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.
