It is of importance to understand how the field is evolving during the propagation through the focal region along the optical axis.
In VirtualLab Fusion, with the Parameter Run, it is possible to perform a scan of the field along a succession of planes, and thus to have access to the complete information of the electromagnetic field inside the focal region. Particularly, all eventual vectorial effects due to high-NA focusing are taken into account.
Focus Investigation behind Aspherical Lens
A laser diode with asymmetric divergence and astigmatism is first collimated and then focused. Evolution of the field in the focal region is investigated in detail.

In VirtualLab Fusion, by using the Parameter Run, it allows a scanning of the field at any plane of interest, and thus you may have access to the complete electromagnetic field information within the focal region. Particularly, all the possible vectorial effects due to high-NA focusing are taken into account.
