Abstract

High power lasers are more and more equipped with unstable resonators. Since an exact analytical treatment is not feasible in all cases numerical calculations are the best way to get beam quality, output power and workload of the resonator mirrors. A typical design process for unstable resonators using a wave propagation program is demonstrated. This programm uses a Fast Fourier Transform together with a Phase Sheet Technique. It allows to calculate the outcoupling factor and the near- and farfield distribution due to local medium inhomogeneities. The influence of potential intracavity adaptive optics is discussed as well.
