How to Work with the Programmable Light Source in VirtualLab Fusion and Example (Gaussian Beam)

Providing maximum versatility for your optical simulations is one of our most fundamental objectives. In this document we show you how to work with the Programmable Source: a means to define the spatial dependence of a custom basic source mode which can then be used on its own, as a fully coherent, monochromatic source; or as a single mode in a more complex one (which is perhaps partially spatially coherent or polychromatic). Although the Gaussian beam is one of the source models included in VirtualLab by default, we use it here as a simple programming example.
