Abstract

The complex behavior of the optical wave in laser resonators requires a comprehensive model of thermal lensing and the dynamic, 3-dimensional behavior of the laser beam. To this end, we perform a combined finite element analysis (FEA) of the optical wave and of thermal lensing. Here, the simulation of the optical wave is the most challenging task. Therefore, we also discuss another method, Dynamic Multimode Analysis, which is suitable for a wide range of lasers. Finally, we present a complex heat model in order to analyze the interaction of heat generation, thermal lensing, laser dynamics, and the beam profile.
