SPATIAL-TEMPORAL BEHAVIOR OF ULTRASHORT PULSES
Time: 2020-01-14 17:55Source: δ֪Writer: infocrops
Ultrashort pulse lasers, with time duration in femtoseconds, are of great importance and potential for both fundamental research and industrial applications. For example, such lasers enable the extremely precise processing of materials, which is known as “cold” ablation. In VirtualLab Fusion, an ultrashort pulse is modeled as a composition of a broadband spectrum, and the correlation between the different spectral modes is considered. That enables the investigation of ultrashort pulse behavior in both spatial-temporal (or spatial-spectral) domain, as shown in the examples below.
 
Pulse Focusing with High-NA Lens

 
We investigate the effects of subjecting an ultra-short pulse to propagation through a lens with high numerical aperture, in terms of its spatial, as well as of its temporal, profile.
Femtosecond Pulse Focusing

 
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.
