„VirtualLab Fusion offers excellent opportunities in research projects and is perfect for use in teaching, especially since there are many documented application examples available.“

Prof. Dr. Stefan Kontermann, Hochschule RheinMain

Nowadays ray tracing is not sufficient anymore. For a detailed analysis physical optics is required. VirtualLab Fusion is optimized for wave-optical simulations. The results we achieved are excellent. We can highly recommend VirtualLab Fusion. Not only the software is great, but also the support of the whole LightTrans team.

Dr. Benjamin Heck, Raylase GmbH

Excellent program, amazing capabilities, and very user-friendly interface.

Galina Machaviariani, Apple

VirtualLab Fusion is a very promising software that is helping in solving some peculiar diffraction issues that have been causing headaches to the community.

Federico Landini, INAF – Osservatorio Astrofisico di Arcetri

This is one of the most elaborate pieces of software I’ve ever had the pleasure of working with. My workflow now is not only faster and more pleasant, but also very well documented with little to no effort on that point.

Dr. Fabian Patrovsky, CDA GmbH

Thermal Lensing in Optical Systems

[April 29, 2021]
In this newsletter we show how VirtualLab Fusion simulates the thermal lensing effect using inhomogeneous media. We demonstrate this effect on various optical components common in material processing applications, like lenses and laser rods.

The advent of modern technologies in the area of material processing has seen an increase in the use of high-power laser sources in optical systems. The massive amount of heat generated by the high-energy sources leads to a deformation of the geometry and a modulation of the refractive index of the optical components in the system that will influence their properties. In VirtualLab Fusion these effects are handled by connecting surface operators with solvers for inhomogeneous media. We demonstrate these effects in various optical components common in material processing applications, like lenses and laser rods.

Modeling of spatially extended partially-coherent source

[April 22, 2021]
In this newsletter we explore the effect of the configuration of the elementary fields and the number of fields. Then we reproduce Young’s interference experiment using this source and investigate the coherence properties of the source by checking the changes in the contrast of the interference fringes.

In this newsletter we explore the effect of the configuration of the elementary fields and the number of fields. Then we reproduce Young’s interference experiment using this source and investigate the coherence properties of the source by checking the changes in the contrast of the interference fringes.

In numerical simulations, when we represent light as an electromagnetic field, spatially extended sources can be modeled by several uncorrelated fully coherent fields, with identical energy density, but partially shifted with respect to each other [J. Opt. Soc. Am. A 27 (9), 2010].  In the fast physical optics software VirtualLab Fusion, we use this method to model a spatially extended partially-coherent source and explore the effect of the configuration of the elementary fields and the number of fields. Then we reproduce Young’s interference experiment using this source and investigate the coherence properties of the source by checking the changes in the contrast of the interference fringes.
