Femtosecond pulses are drawing more and more attentions in modern optical applications, because of their ultrashort temporal duration and the corresponding ultrahigh power. The ultrashort temporal duration also leads to broad spectrums. Such spectral or temporal properties of femtosecond pulses must be properly handled together with their spatial behaviors for the modeling.
VirtualLab Fusion provides such a physical-optics simulation platform capable of femtosecond pulse modeling.
Femtosecond Pulse Propagation through Dispersive Seawater
The propagation of a 5 fs pulse through seawater is studied in VirtualLab. 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 in VirtualLab, and both the spatial and temporal behaviors are investigated.
