Propagation through Microlens Arrays

[September 23, 2021]
In VirtualLab Fusion such systems can be setup and simulated using a new MLA component introduced in the latest release, allowing a thorough investigation of the transmitted field in the near field behind the microlens component as well as in the far field and focal region.
[September 23, 2021]

With the advent of modern technologies specialized optical components like microlens arrays (MLAs) get more and more attention. Especially in the field of optical projection systems, material processing units and optical diffusers microlens arrays have seen common usage. In VirtualLab Fusion such systems can be set up and simulated using a new MLA component introduced in the latest release, allowing a thorough investigation of the transmitted field in the near field behind the microlens component as well as in the far field and focal region.

Focusing of different types of Gaussian modes by thermal lens

[September 03, 2021]
In this examples, the light is focused by a thermal lens, because the effect of thermal lensing can often be encountered in high-energy laser beam applications.
[September 03, 2021]

In high-power laser applications one commonly encountered effect is focusing by thermally induced lenses. While usually this effect is detrimental, it can also be used for specific applications. For instance in the field of optical tweezer and particle trapping Ince Gaussian Modes are utilized as their beam profile maintains even when propagated through a focus. With the newly introduced Ince Gaussian Mode Source and the Inhomogeneous Media Component such applications can now also be simulated in VirtualLab Fusion. Moreover, the accurate physical optics propagation techniques, inbuilt in VirtualLab Fusion, enable the detailed analysis of focal regions, especially for different types of Gaussian modes and complex focusing elements like thermal lenses.

Ince-Gaussian Beams

[September 03, 2021]
Ince-Gaussian modes are 3rd complete family of exact and orthogonal solutions of the paraxial wave equation.
[September 03, 2021]

Ince-Gaussian modes are the third complete family of exact and orthogonal solutions of the paraxial wave equation alongside the Hermite-Gaussian and Laguerre-Gaussian modes. As they tend to maintain their beam profile even while propagating through a focus, they see common use in optical tweezer and atom trap applications.

In the newest release of the fast physical optics modeling and design software VirtualLab Fusion we have introduced a new source to easily set up this kind of source modes, as demonstrated in the examples below.
