Ince Gaussian Modes

Apart from Hermite- and Laguerre-Gaussian modes there is a third kind of rigorous and orthogonal solution family for the paraxial wave equation – the so-called Ince-Gaussian modes. These solutions are defined in elliptical coordinates and have the benefit of allowing for a transition between Hermite- and Laguerre-Gaussian modes by means of an elliptical parameter. These modes have advantages in the area of optical tweezers and particle-trapping applications. This use case presents the Ince-Gaussian Beam Source in VirtualLab Fusion and shows how to define an individual mode.
