Customizable Parameter Run and Parameter Coupling

[August 15, 2018]
To evaluate the actual performance of optical systems, it often requires the inclusion of complex real-world parameters e.g. fabrication errors, misalignment, and even thermal/vibrational perturbances. The Parameter Run in VirtualLab Fusion allows the definitions of such parameters in a completely customizable manner according to the specific case. Moreover, optical parameters may mutually influence each other, so that they change, not independently, but in a coupled way. VirtualLab also provides a customizable Parameter Coupling for the definition of possible coupling relations.

Modeling of Femtosecond Pulses

[August 01, 2018]
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 provide such a physical-optics simulation platform that is capable of femtosecond pulse modeling.

Vectorial Effects in High-NA Focusing Systems

[July 30, 2018]
[July 30, 2018]

In high-NA focusing systems, the vectorial nature of light starts to play a non-negligible role and it may affect the focal spot. Input polarization, the direction-dependent Fresnel coefficients at the surfaces and the diffraction effect that dominates the propagation of the field in the focal zone must all be considered in order to make reasonable predictions about high-NA setups.

In VirtualLab, all these effects can be included for the investigation of your system, and the focal fields can be calculated very efficiently.

Design of Refractive Beam Shapers

[July 30, 2018]
Refractive beam shapers are of great help in several laser-related applications. For example, in material processing, the laser beams are often required to have uniform distributions, like top-hat, on the target plane. In VirtualLab, refractive beam shapers can be designed by using a user-friendly workflow, and the design results can be exported into those formats which are ready for fabrication purpose.

Thermal Lens and Stress-Induced Birefringence

[July 30, 2018]
It is vital in design to be able to include in your simulation not only those properties or components that play an intentional, wanted role in the system, but also, and with particular care, those effects which have the potential to interfere with its intended purpose, in order to quantify and, if possible, avoid them. Below we show two examples of VirtualLab’s potential in this area: all thanks to its fast and accurate approach, and an interface that allows you both to import measured data (from, e.g., ANSYS) or to include the effects via readily available or customized mathematical models.
