VirtualLab Fusion Technology

VirtualLab Fusion introduces groundbreaking geometric field tracing technology. It constitutes a fast Maxwell solver inspired by ray optics and can be smoothly combined with numerous diffractive field tracing methods.

VirtualLab Fusion is designed to take you through your simulations in a step-by-step process. Start with ray tracing to investigate the basic performance of your optical system. Next, switch to geometric field tracing and quickly obtain additional information about your field values including intensity, phase, polarization, coherence, and inter­ference. Finally, combine geometric with diffractive field tracing techniques to include more wave optical effects in your simulation. You can learn more about fast physical optics modeling from the following two papers:

Model of a beam delivery system for the focusing of a single mode diode laser beam and the electric field in the focal region
