Focusing of an Ince-Gaussian Beam

Ince-Gaussian modes are a well-known exact and orthogonal solution family for the paraxial wave equation. This kind of source mode can be advantageous for different applications in the areas of optical tweezers and particle trapping. In this use case we demonstrate the focal properties of the Ince Gaussian Beam Source in VirtualLab Fusion by propagating the modes through a GRIN medium. This medium represents a thermal lens, an effect which can be encountered often in applications for high-energy laser beams.
