How to Work with the Programmable Medium and Example
(Thermal Lens)
Abstract
Providing maximum versatility is one of our most fundamental objectives. A key aspect of this aim is to provide a flexible-enough definition mechanism of the refractive index, in order to achieve a realistic characterization of the matter which composes an optical system.
In VirtualLab Fusion this role is left to Materials and Media: the first deal with the dependence of the refractive index on wavelength (dispersion), the second group take care of the dependence on position. Here we bring you a tutorial that explains how to program your own custom media.

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].
