Focusing of an Ince-Gaussian Beam
Abstract
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.

Use Case
Gaussian Beam Focused by a Thermal Lens
This use case shows the variation of the focal length of the thermal lens, as well as the focus beam diameter when the input power changes [W. Koechner, Appl. Opt. 9, 2548–2553 (1970)]. This example is published in [H. Zhong, J. Opt. Soc. Am. A 35].
Use Case
Ince Gaussian Modes
Ince-Gaussian Modes constitute an additional solution for the paraxial wave equation. This use case shows how to set up this kind of modes.
