Abstract

Thermo-optical simulation is a compulsory improvement of classical ray tracing, since many branches of optical and laser technology have to deal with thermal gradients. This paper discusses an approach for coupling FEM and ray tracing simulation tools by processing FE data using scattered data approximation techniques. The implemented interface for two space dimensions is being validated by comparing approximated data to measured values from a CO2 laser application of up to 1.75 kW. Finally, the benefits and further developments of analyzing thermal gradients in optical simulation are being discussed.
